protons and neutrons
An atom with its outermost shell completely filled is likely to be stable and unreactive. This is because the full outer shell provides a balanced charge, making the atom less likely to gain or lose electrons.
if the atom is an element from groups 1, 2, or 13, the atom has to give up electrons to make it have 8. For example, if you have Boron in group 13, it has 3 valence electrons, making it more likely to give up electrons than gain them. If you take 3 electrons from Boron, you get Helium. Helium is the noble-gas for Boron. B(+3) has a noble-gas configuration of He. if the atom is an element from groups 15, 16, or 17, the atom has to gain electrons to make it have 8. For example, if you have Oxygen with 6 valence electrons, it is more likely to gain electrons than lose them. If 2 electrons are added to Oxygen the noble-gas configuration becomes Neon. O(-2) has a noble-gas configuration of Ne. if the atom is an element in group 14, it can either gain or lose electrons. so the noble gas configuration could be the 4 electrons less or 4 electrons more than it. For example, if you add 4 electrons to Carbon you get Neon but if you take away 4 electrons you get Helium.
Metals give up electrons while non-metals gain electrons
their atoms take,give,or share electrons with other atoms :)
Atoms can gain or lose electrons to become charged particles called ions. When atoms gain electrons, they become negatively charged ions, while atoms that lose electrons become positively charged ions. This transfer of electrons allows atoms to achieve a more stable state by filling their outer electron shell.
the valence electrons take place i.e, the electrons present on outermost shell.
The bond formed when two atoms have a give-take relationship in relation to electrons is called ionic bonding. This will mostly happens so that atoms can gain stability.
If you mean two atoms are sharing electrons, then a covalent bond is formed.
A bond where electrons are shared between atoms. These atoms usually have similar electronegativities, so one atom doesn't take all of the electrons from the other. The opposite of covalent would be ionic, where one atom does take electrons from the other.
In a triple bond, a total of six electrons are shared between two atoms. Each atom contributes one electron for a sigma bond, and two atoms contribute two electrons each for two pi bonds.
In a triple bond between two atoms, a total of six valence electrons take part. Two electrons come from each atom to form the sigma bond, and the remaining four electrons form two pi bonds.
more electrons because all atoms want to be like noble gases and will either give or take electrons to obtain 8 electrons so atoms with either 1 or 2 electrons would wither give off 1 or 2 electrons depending on how many then had
