Yes, bonds and reactions are caused by the valence electrons only (the outermost principle energy level).

What is the result of sharing of electrons in the outer energy levels of two atoms?

Sharing of electrons in the outer energy level of two atoms results in a covalent bond.


Why is mercury poor at sharing electrons?

Mercury has 80 electrons distributed in 6 energy levels,; namely:First Energy Level: 2Second Energy Level: 8Third Energy Level: 18Fourth Energy Level: 32Fifth Energy Level: 18Sixth Energy Level: 2Accordingly, Mercury has on the outer shell 2 electrons to share with in any chemical reaction by an ionic bond.


What type of bond shares electrons to fill the outermost energy level?

The sharing of electrons occurs in covalent bonding.


Explain how valence electrons in an atom are used to form a full outermost energy level?

Atoms form chemical bonds to achieve a full outermost energy level by sharing, gaining, or losing electrons. Valence electrons are the electrons in the outermost energy level of an atom, and having a full outermost energy level makes the atom more stable. This stability is achieved when there are eight electrons in the outermost energy level, known as the octet rule.


What is one way atoms fill their outermost energy level?

Atoms can fill their outermost energy level by either gaining electrons from other atoms or by sharing the outermost electrons with another atom.


What happen when an atom has more electrons that can fit in one energy level?

An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.


How many electrons are in the outermost energy level of carbon and how many does it need to have this energy level filled?

Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.


What is the outer most energy level of an atom?

This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.


How many electrons are in the third energy level of helium?

Oh, dude, helium only has two electrons total, so there can't be any in the third energy level. It's like trying to fit a square peg in a round hole - just not gonna happen. So, zero electrons in the third energy level of helium.


How many electrons in magnesium's third energy level?

Magnesium has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level, for a total of 12 electrons.


How many electrons does argon have in each of its energy levels?
