Why do elements want to have a filled outer shell of electrons?

To achieve greater stability, atoms will tend to completely fill their outer shells and will bond with other elements to accomplish this goal by sharing electrons, accepting electrons from another atom, or donating electrons to another atom.

Why do elements react to have a full valence shell?

A complete octet is very stable because all orbitals will be full. Atoms with greater stability have less energy, so a reaction that increases the stability of the atoms will release energy in the form of heat or light. Thus, an atom continues to form bonds until an octet of electrons is made.

Why do all elements try to get a full outer shell like the noble gases?

Atoms want a full outer shell because it completes all the gaps in the outside. With no gaps, other electrons don’t want to fit into those spaces. For example, a noble gas like Neon has a full outer shell. It doesn’t react with other chemicals because the electrons from other chemicals can’t fall in anywhere.

Which elements have a full outer shell of electrons?

Group 18 elements (helium, neon, and argon are shown) have a full outer, or valence, shell. A full valence shell is the most stable electron configuration.

When atoms complete their outer shells?

In general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.

When elements react their atoms join with other atoms what type of substance is formed?

When elements react, their atoms join with other atoms to form compounds. Some compounds are made from metals combined with non-metals, for example sodium chloride and magnesium oxide.

What is a full valence shell called?

The exterior shell of an atom is called the shell of valence. It becomes complete when a shell ends its duplet or octet, or we may assume that a full outermost shell is reached. Since helium only contains two electrons. They exist, however, only in the first shell, which involves the completion of only two electrons.

What would likely happen to an atom when it has a full valence shell?

This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons. In general, atoms are most stable, least reactive, when their outermost electron shell is full.

What is a full outer shell of an atom?

A full outer shell is known as the noble gas configuration where the outer shell of an atom is energetically stable and contains 8 outer electrons.

When atoms complete their outer electron shell by gaining or losing electrons they form?

An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons. Covalent bonds form when sharing atoms results in the highest stability.

When atoms complete their outer electron shell by sharing electrons they form Bonds?

Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.

When 2 elements react together they make a?

When elements react together to form compounds their atoms join to other atoms using chemical bonds. For example, iron and sulfur react together to form a compound called iron sulfide. Mixture of iron (grey) and sulfur (yellow) powders. Compounds usually have different properties from the elements they contain.
