Answer:
A neutral Beryllium atom has two (2) valence electrons
Explanation:
<em>Beryllium, Be,</em> is a group 2 element on the periodic table. Its atomic number is 4.
Generally, atomic number equals number of electrons, which means a neutral Beryllium atom contains four (4) electrons: two (2) in the inner shells and 2 in the outer shell (valence electrons), which can take part in a chemical reaction and participate in chemical bonding.
