What are three ways an atom can gain stability?

Answer 1

To be chemically stable, the atom must have the same amount of protons and electrons.

An atom can become stable by either 1) losing an electron, 2) gaining an electron, or 3) sharing electrons (this only happens between two molecules)

Answer 2

The stability of an atom means complete outermost shell or octet this may be acquire by three ways, 1- by gain of electrons, 2- by loss of electrons and 3- by sharing of electrons.
By bonding with atoms which have the appropriate valencies needed.
Unstable atoms, like your alkaline metals(correct me if I'm wrong) gain stability by finishing off their valence electron count, in the outer most shell that orbits around the nucleus. the first electron shell can hold 2 electrons, 2nd can hold eight, etc. So for example, Carbon has 6 electrons. That means that its first shell is filled and the second is half-way filled.Because it needs 8 valence electrons in that second shell to be stable, it will search for 4 bonds with say hydrogen. Hydrogen only needs one bond, so it would have to pair with 4 hydrogens to be satisfied. The more filled the valence shell, or last shell, is filled, the more stable it will be.

Answer 3

STABLE AND UNSTABLE ATOMS:Just like sodium, it has 1 electron on the outer shell and 8 in 2nd shell so it will donate one electron to another atom to become stable similarly chlorine have 7 electrons on the outer shell so it could gain the electron to become stable.

Here area list of ways atoms could be stable and unstable

1. Eelectromagnetic fields cause like charges to repel each other and unlike charges to attract each other.2. The protons stay together in the nucleus because the strong force opposes and overcomes the forces of repulsion from the electromagnetic field.3. Binding energy is the energy that is associated with the strong force, and this energy holds the nucleus together.4. A stable atom is an atom that has enough binding energy to hold the nucleus together permanently.5. An unstable atom does not have enough binding energy to hold the nucleus together permanently and is called a radioactive atomAlso, if you want to know the elements in the periodic table there is a chart attached to this:

Answer 4

atoms become stable because they combine to other atoms

Answer 5

Atoms become more stable by forming bonds with other atoms. The atoms will do this by gaining or losing electrons.

Answer 6

1. lose one or more electrons

2. pick up one or more stray electrons

3. form a chemical bond so that it can share one or more electrons
