an ionic compound is formed
1. Rubidium don't gain atoms ! 2. If you think to electrons rubidium loss one electron and becom a cation.
Lithium does not have a '0' charge. Its electron configuration is 2,1. This means there is one valence electron in its outer shell. Losing this electron will make Lithium have a full shell (2 only) which all atoms try to achieve, therefore Li has a +1 charge because it loses an electron to gain noble gas configuration.
Boron can lose 3 electrons from its valence shell that is 2 in 2s & 1 in 2p sub-shell, wheras it cannot gain electron b'coz of its electropositive nature & it has less electron affinity.
No. Magnesium Chloride (MgCl2) is an ionic compound. Magnesium loses 2 electrons and the two chloride atoms gain one each.
In the simplest sense, an atom can either gain or lose an electron to become more stable. Very electronegative atoms like fluorine and oxygen tend to gain electrons, whereas atoms that are less electronegative like the alkali metals tend to lose electrons. In these cases, an electron is sent to a lower energy state, thus making the atom more stable.
1. Gain an electron. 2. Lose an electron.
Calcium usually loses 2 electrons, giving a cation of Ca2+

When an atom gains or loses electrons, it gains a negative or positive charge respectively. Atoms generally try to gain enough electrons to fill their outer, valence electron shell. For the first shell the number of electrons is 2 and for all others, atoms usually want 8 electrons.
When it gain electrons, it loses ions. (non-metal) Where as when it loses electron, it gains ions. (metal)
Lithium does not have a '0' charge. Its electron configuration is 2,1. This means there is one valence electron in its outer shell. Losing this electron will make Lithium have a full shell (2 only) which all atoms try to achieve, therefore Li has a +1 charge because it loses an electron to gain noble gas configuration.
Barium loses electrons to obtain a stable octet, like any other metal.
Lithium has one valence electron. It is much easier for an atom to lose one electron than gain seven more. Lithium looses this one electron to achieve a full outer shell (the next inside shell is full).
This is by gaining (-) or losing (+) electrons
Because calcium has 2 valence electrons, it needs to get rid of them to have a stable noble gas conformation. Chlorine atom has 7 VE and only needs to gain one electron to have the noble gas conformation. Therefore one calcium will give one electron to two chlorine atoms, therefore resulting in an ionic bond.
Boron can lose 3 electrons from its valence shell that is 2 in 2s & 1 in 2p sub-shell, wheras it cannot gain electron b'coz of its electropositive nature & it has less electron affinity.
