What element has 4 protons and 2 electrons?
Beryllium (Be) has 4 protons and 2 valence electrons.
How many valence electron does Ca have?
Calcium's atomic number is 20. It therefore has 20 protons and 20 electrons. Since calcium is a group 2 element, 2 of those electrons are valence electrons.
How many electrons does the element Be have in it?
4 electrons, 2 valence electrons
What element has 118 and 8 valence electrons?
Ununoctium has 118 electrons including 8 valence electrons.
How many valence electrons are in zirconium atom?
protons:40electron:40neutrons: can vary, however, the main isotope has 80

How many electrons does the element Be have in it?
4 electrons, 2 valence electrons
What element has 118 and 8 valence electrons?
Ununoctium has 118 electrons including 8 valence electrons.
What is the valence number for helium?
He has 2 valence electrons. Look on a periodic table. It will show He only has 2 protons and the number of protons and electrons is equal. It is an exception to the rule of group numbers corresponding to valence numbers.
