Based on the electron configuration of the two atoms, predict the ratio of metal cationic (+) atom
to nonmetal anionic (-) atom in the compound.
Beryllium 1s22s2
Chlorine 1s22s22p%3s23p5
A. 2:3
B. 1:2
C. 2:1
D. 3:2

The correct answer is c. orbital shape. "the angular momentum quantum number l describes the shape of an orbital. it corresponds to each orbital type, i.e. (0,1,2,−1)=(s,p,d,f,g,"

The total number of nucleons

What do you need with it’s not a question your just stating what it says

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).
