Bohr diagram |
Protons,Electrons,and Neutrons |
18 electrons so 8 are on the valance and the element is stable.
A.P.E M.A.NAtomic Number is equal to Number of Protons and Electrons.
To get your Neutrons you need to use Mass number-Atomic number=Neutrons.40-18=22 |
Protons and electrons are 18,and neutrons 22 after you do M-A=N.
Group and period,periodic table and elementPeriod 3 and group 18.its a noble gas and a non-metal.
