Zero. Neon is an inert gas and is atomically stable.
Neon is already a stable element with a full outer electron shell, so it does not need to gain any electrons to achieve stability. Neon has 10 electrons in total, with a full valence shell of 8 electrons. Therefore, it is already in a stable configuration.
it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
4 protons 4 electrons 5 neutrons subtract the number of of protons from the atomic weight
Aluminum needs to lose 3 electrons to gain a noble gas electron configuration.
It needs to lose, or gain, electrons.
since the atomic number is 7, and the first full layer takes 8 electrons, it needs 1 electron
It can be created a metal atom that needs electrons to fill its valency shell for stability comes in contact with a non-metal atom that has spare electrons to give in order to achieve the same form of stability.
The atom needs to have the same number of electrons as it has protons.
Nitrogen has two energy levels. The first energy level contains two electrons. The second energy level contains five electrons. Number of Protons/Electrons: 7 Number of Neutrons: 7
it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
Silver needs 7 more electrons to reach a "pseudo-noble gas" configuration.
Jody needs more stability in her home.
The number of electrons in a shell is 2n2, where n=shell number. So for the first shell, there is a maximum of 2 electrons.
atoms are most stable when they have filled the outer shell of electrons which normally holds a max of 8. so if an atom has 1 electron in its outer layer getting rid of it will give him stability, in much the same way having 7 electrons will mean gaining one electron will give it stability. now lets say the two meet, they react with each other and everybody is happy. It is thought than when two elements react, they are trying to acheive a "perfect" electronic configuration (i.e. have a full outer shell). The more electrons needs to lose/gain before acheiving this stability determines its reactivity.

The atomic number tells you the number of protons and electrons there are in an atom of any given element. Some people refer to it as the "proton number". The number of protons and electrons needs to be equal in order to ensure that the atom has no charge.
Stability system needs service?
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
