Question

Write the electronic configuration, numer of protons, electrons and neutrons : 24mg12, 25na11

Answer 1

Mg =2,8,2 and for Na =2,8,1

Answer 2

for magnesium electrons are 12 and the electronic configuration is 2,8,2 and the number of neutrons is 12 ...
for na or sodium electrons are 11 and the configuration is 2, 8, 1 and neutrons are 14..protons are the same as electrons so their numbers are equal to electrons
