an atom with atomic number 20 has 20protons. it has 20 electrons because the number of protons is equal to the number of electrons in the nucleus of an atom.

Parrain

An atom with an atomic number of 20 will have to have 20 electrons in order to make it balanced.

The atomic number of an atom:

  • Represents the number of protons in the nucleus
  • Is used to identify an atom as atoms have unique atomic numbers

The number of protons in an atom must equal the number of electrons in order for the atom to have no charge.

As there are 20 protons in this atom because the atomic number is 20, there will have to be 20 electrons to balance it out.

In conclusion, an atom with an atomic number of 20 will have 20 electrons.
