It predicts and lists all chemical elements in the universe. What do electrons in the same shell have in common? They all have the same amount of energy. ... They cannot be broken apart without losing their chemical properties.
Explanation:I took a quiz on it
N, Ne, F, B, Li
Valence electrons are the electrons that are found in the outermost shell in a neutral atom. These five elements are the only one whose valence electrons fall on the same shell. The second shell. Their electronic configurations are as follows:
They have the same amount of energy
They cannot be broken without losing their properties.
they have the same quantity of energy...
They have the same amount of energy. They are all positively charged. They are all made up of atoms.
