Answer:
Elements with unpaired valence electrons in the outer orbital are paramagnetic. Elements that are predicted to exhibit paramagnetic behavior may exhibit ferromagnetic behavior. Elements that contain only paired valence electrons are diamagnetic.
Answer:
water is not a solid and a rock is a solid
Magnesium (Mg) has atomic number 12 with electronic configuration :
The valence shell of Mg is 3s which has 2 electrons as shown in above electronic configuration.
Therefore, A = 3 and B =2
I think it's RbCl and CaO
Answer:
true
Explanation:
because if you really take a moment to think about it atoms are made of molecules.
