## What is the mass number of an atom of potassium that has 20 neutrons?

39
An atom of potassium with 20 neutrons would have a mass number of 39 and thus be an atom of the potassium-39 isotope.

## How do we find atomic mass?

For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

## What is the mass of 1 amu?

In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass. This is approximately 1.67377 x 10 27 kilogram (kg), or 1.67377 x 10 24 gram (g). The mass of an atom in AMU is roughly equal to the sum of the number of protons and neutrons in the nucleus.

## What is the mass bumber of an ion with 109 electrons 159 neutrons and a 1+ charge?

## What is the mass number of an ion with 106 electrons and 159 neutrons?

Answer Expert Verified Here the ion has 105 electrons and 159 neutrons and +1 charge. This means the original atom has lost one electron, originally there are 106 electrons in the neutral atom which shows that there are also 106 protons because in neutral atom protons and electrons are same. 265 is the mass number.

## How do you find the mass number of electrons and neutrons?

The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

## How do you find mass number without neutrons?

The atomic mass is the weighted average mass of all the isotopes of an element. If we round off the atomic mass to the nearest whole number and subtract the atomic number from it, we get the number of neutrons. That is, number of neutrons = atomic mass (rounded to nearest whole number) – atomic number.

## How do you find electrons?

To calculate the numbers of subatomic particles in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number.

## What element has 159 neutrons?

seaborgium 265
For example, seaborgium 265, which has a nucleus containing 106 protons and 159 neutrons, decays to rutherfordium 261, which decays to nobelium 257.

## Whats an atomic ion?

An ion is a charged atom or molecule. … When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.

## What is the atomic number of an atom that has 6 protons 6 neutrons and 6 electrons?

## What is the chemical symbol of seaborgium?

Seaborgium/Symbol
Seaborgium is a synthetic chemical element with the symbol Sg and atomic number 106. It is named after the American nuclear chemist Glenn T. Seaborg.

## How do you find the atomic number?

Now you know that atomic number = number of protons, and mass number = number of protons + number of neutrons. To find the number of neutrons in an element, subtract the atomic number from the mass number.

## What particle has 50 protons and 46 electrons?

Sn Atomic Number is 50, so it has 50 protons…and since it is missing 4 electrons, it has 46 electrons. The atomic mass is 118.7 g/mol, so it’s mass number is 119. Neutrons = 119 – 50 = 69 neutrons.

## What are polar attractions?

Polar attractions occur between atoms with partial charges and are weaker than covalent bonds. … They can also form between H and other highly electronegative atoms, such as O, if the atoms have strong partial charges.

39.0983 u

## How do you find the mass number of potassium?

The mass number of an element is determined by adding the number of protons and neutrons in the atom. Potassium is atomic number 19 on the periodic table. The atomic number is equal to the number of protons. Atomic number 19 = 19 protons.

## What mass number is 19?

fluorine
The chemical element fluorine is a gas that has a mass number of 19.

## How do you write the atomic number and mass number?

To write the notation of an atom, we need to know the symbol of the element, the atomic number and the mass number. The mass number of the atom goes above the symbol and the atomic number is written as a subscript.

## What is mass number example?

(ii) Mass number: It is the sum of the number of neutrons and the number of protons. For example, the atomic number of Lithium is 4 which is equal to the number of protons, the number of neutrons of magnesium is 4. The mass number is equal to 8(4+4).

## What is atomic mass in chemistry?

Lr. The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
