Using the periodic table, complete the table to describe each atom. Type in your answers. A

B

C

D

E

F

This is what I think, so hopefully it's right!

A= 8 B= 8 C= 0 D= 26 E= 30 F= Fe

I hope this helped! :)

the correct option is c.

isotopes refers to different forms of the same element with the same atomic number but different mass number as a result of difference in their neutron numbers. isotopes have different relative atomic mass but share the same chemical properties.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
