3. (3 pt) Select a valid excited state electron configuration for an uncharged atom of C.

a. 1s 2s22p

b. 1s22s22p2

C. 1s22s22p+352

d. 1s22s22p1

e. There's no way to tell

hi,

the capital city of australia is canberra.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock

c. electrical charges of ionic bonds.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
