The number of neutrons is variable.
Ununoctium has 118 protons, 118 electrons and 176 neutrons.
one valence electron
Calcium has 2 valence electrons
They don'tThey group elements with the same number of valence electrons.The valence electrons of an element determine how that element bond and how many bonds it forms.So elements with the same number of valence electrons tend to have similar chemical properties.
Boron has 3 valence electrons.Boron has 3 valence electrons.
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
