Contents

What does 2 protons and 2 electrons make?

Helium
In its neutral state, Helium has two electrons in orbit about the nucleus. Model of a helium atom’s nucleus with two protons and two neutrons. Helium is a relatively inert element, which when in its neutral state is quite unreactive due to a filled outer shell of electrons.

What does a sulfur atom become when it gains 2 electrons?

Therefore a sulfur atom will gain two electrons to form the sulfide anion with a charge of 2− , with the symbol S2− .

What happens when you add or remove protons from an atom?

Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom’s atomic number. So, adding or removing protons from the nucleus changes what element that atom is!

How many electrons will Sulfur gain or lose when it forms an ion?

Sulfur would need to gain 2 electrons in order to achieve an octet configuration. Unlike in the calcium example presented in the previous section, gaining this number of electrons is possible, as doing so would not exceed the maximum gain-limit of three electrons.

What element has 2 electrons 2 protons and 2 electrons?

helium

What is the charge of 2 protons 2 neutrons and 2 electrons?

Neutrons have no charge. Since the numbers of protons and electrons are equal, the positive charge of the protons and the negative charge of the electrons add up to zero. 2p++ 2e− = 0 . Therefore, a helium atom with two electrons, two protons, and two neutrons has no charge.

What happens when a sulfur atom is converted to S2?

Which of the following occurs when a sulfur atom is converted to S2-? The sulfur atom gains two electrons. … What bond angle is most closely associated with a tetrahedral distribution of electron density?

What would be the electron configuration of a sulfur ion S − 2?

S: 1s2 2s2 2p6 3s2 3p4 S2- : 1s2 2s2 2p6 3s2 3p6 Note: Replacement of 1s2 2s2 2p6 by [Ne] is acceptable. One point is earned for the correct configuration for S. One point is earned for the correct configuration for S2-.

Does sulfur gain 2 electrons to form a cation?

We can also find the number of valence electrons by checking sulfur’s group number, group 16, which has a 6 in the 1s place. That means that a neutral sulfur atom will need to gain two electrons to reach a full octet of eight electrons. Therefore, we predict that the most common charge on a sulfur ion will be 2-.

What happens when you add or remove electrons?

When electrons are added to an atom, the increased negative charge puts stress on the electrons already there, causing energy to be released. When electrons are removed from an atom, that process requires energy to pull the electron away from the nucleus. Addition of an electron releases energy from the process.

What happens when you add or remove neutrons?

If you add or subtract a neutron from the nucleus, you create a new isotope of the same element you started with. In a neutral atom, the number of positively charged protons in the nucleus is equal to the number of orbiting electrons.

How can protons be removed from an atom?

The only two ways by which atoms lose protons is through radioactive decay and nuclear fission. Both processes will only occur in atoms that have unstable nuclei.

Can sulfur lose or gain electrons?

Most nonmetal atoms, including sulfur, tend to form anions, which means they gain, not lose electrons, to fill its octet.

How ions gain or lose electrons?

Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.

What is the charge on an ion of sulfur if one sulfur atom loses two electrons?

2−
For each electron gained, the ion’s overall charge decreases by 1 unit, which further confirms the fact that the neutral sulfur atom gained 2 electrons to get the (2−) charge.Nov 6, 2016

What element has 2 protons 3 neutrons and 2 electrons?

All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. For example, all helium atoms have two protons, and no other elements have atoms with two protons.

What is the charge of an atom that has 2 protons and 1 electron?

As summarized in Table 2.1, protons are positively charged, neutrons are uncharged and electrons are negatively charged. The negative charge of one electron balances the positive charge of one proton.

What is the charge of 2 protons?

If the atom contains 2 protons, 2 positively charged nuclear particles, then Z=2 , and the element is helium by definition. The number of electrons determine if the element is neutral or charged. And since the number of electrons equals the number of proton, this element is uncharged.

When an atom of sulfur becomes an ion It electrons and has the electron configuration of?

The nearest noble gas to sulfur is argon, which has an electron configuration of: 1s22s22p63s23p6. To be isoelectronic with argon, which has 18 electrons, sulfur must gain two electrons. Therefore sulfur will form a 2- ion, becoming S2.

When a sulfur atom becomes a sulfide ion?

Sulphur in its ionic form exists as S2−, because it accepts two electrons to form Sulphide ions. We can see in the reaction that the Sulphur molecule accepts two electrons to become Sulphur ions. Hence, the Sulphur molecule is converted into Sulphur ion, when it (A) gains two electrons.

What is the correct electron configuration of the ion formed by sulfur?

The electron configuration for sulfur is 1s2 2s2 2p6 3s2 3p4.

What atom matches this electron configuration 1s 2 2s 2 2p 6 3s 2?

Is Sulphur a cation?

You can often determine the charge an ion normally has by the element’s position on the periodic table: The alkali metals (the IA elements) lose a single electron to form a cation with a 1+ charge.

Positive and Negative Ions: Cations and Anions.
Family Element Ion Name
Sulfur Sulfide anion
VIIA Fluorine Fluoride anion
Chlorine Chloride anion
Bromine Bromide anion

Is sulfur likely to form a cation or anion?

Halogens always form anions, alkali metals and alkaline earth metals always form cations. Most other metals form cations (e.g. iron, silver, nickel), whilst most other nonmetals typically form anions (e.g. oxygen, carbon, sulfur).

What happens when a sulfur atom becomes an ion?

Main group metals retain their name when forming cations. … However, when non-metallic elements gain electrons to form anions, the end of their name is changed to “-ide.” For example, a fluorine atom gains one electron to become a fluoride ion (F), and sulfur gains two electrons to become a sulfide ion (S2).

How does an atom change if you remove an electron?

If we remove an electron from a stable atom, the atom becomes electrically incomplete/unbalanced. That is, there are more protons in the nucleus (positive charges) than there are electrons (negative charges). With an electron removed, the atom possesses a plus one charge, therefore it is a positive ion.

How does removing an electron change an atom?

Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.

How are electrons removed from an atom?

Ionization is the process in which one or more electrons are removed from an atom or molecule, thereby creating an ion. … In order to remove an electron from an atom, enough energy must be supplied to break the bond between the negatively charged electron and the positively charged nucleus; this is the ionization energy.
