Is argon a diatom?

No, argon exists as single atoms as it has a full outer shell (full octet)


Which of the atoms below dont always obey the octet rule?

H and l


What states that atoms tend to gain lose or share electrons in order to achieve a full set of valence electrons typically?

The octet rule.


How many electrons does each atom desire?

Atoms do not actually have desires as such, although the metaphor can be useful. Atoms are more stable when they have a full outer electron shell.  The smaller atoms, hydrogen, helium, lithium, and beryllium, can obtain a full outer shell with only two electrons in it.  The heavier atoms require 8 electrons to have a full outer shell.  That is known as the octet rule (an octet is a set of eight).


What atoms dont always obey the octet rule?

Hydrogen does not obey the octet rule. Boron does not always obey the octet rule and in fact forms Lewis acids such as BF3 which only has 6 electrons.


What does atoms have to do to fill the outermost energy level?

they need to either gain or lose electrons to create an octet. It depends on the atom. an octet is when an atom has a full outermost energy level


Why do atoms share gain or lose electrons?

Atoms gain, share, or lose electrons to try and become more stable. Atoms will gain, share, or lose electrons until they have a stable 8 valence electrons in their outer shell which is called an octet, which is stated in the octet rule. See the attached links for information on the octet rule.


What are 3 atoms are exceptions to the octet rule?

Boron is one. It exceeds the octet rule.


What two atoms have octet?

CArbon and Oxygen


Why would two oxygen atoms want to form a double covalent bond?

A lone oxygen atom has 6 electrons in its outer shell which is not very stable, whereas as full octet (8 outer shell electrons) is stable. In order to achieve this two oxygen atoms will share 4 electrons, each contributing 2 electrons. Since these electrons exist within the orbitals of both atoms, to oxygen atoms essentially achieve a full octet.


Do metals gain electrons to have full octet?

No, metals tend to lose electrons to achieve a full octet.


Atoms can achieve a full octet of electrons by doing what?

By bonding with another atom, either ionically (donates/receives electrons) or covalently (electron sharing).
