Acation is larger than it was as a neutral atom because the added electrons occupy a higher energy level. true false

False. Cations lose electrons, so they are smaller than the neutral atom.

False

Explanation:

Cation is formed from an atom by the loss of electrons.  

For e.g., Na loses an electron to form Na+

Na – e → Na⁺

The electron configuration of Na: 1s² 2s² 2p⁶  3s¹

The electron configuration of Na⁺: 1s² 2s² 2p⁶

In the formation of Na⁺ there is a loss of electron from the 3s orbital. As a result the size of the Na⁺ ion is less than Na atom.

we need the questions , i may then you.

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!
