An electrically neutral atom of beryllium has four protons.

Which Statement is true?

-There are four neutrons in the nucleus. - There is a charge of + 4 on an atom of beryllium. - There is a charge of - 4 on an atom of beryllium. - There are four electrons.

Answer: The correct statement is there are four electrons

Explanation:

A neutral atom has equal number of protons and number of electrons. This number determines the atomic number of the atom.

Beryllium is the 4th element of the periodic table.

Number of protons in Be-atom = 4

Number of electrons in Be-atom = 4

Hence, the correct statement is there are four electrons

The correct answer is

There are four neutrons in the nucleus of beryllium there are four electrons
