It doesn't lose or gain
Silver is a metal therefore it loses an electron when it reacts to form Ag+
gain
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
When atoms combine with other atoms, some times they lose electrons, some times they gain electrons, and some times they share electrons. In an ionic bond, one atom will lose an electron(s), and the other will gain an electron(s). An example might be NaCl where Na loses an electron and Cl gains an electron. In a covalent bond, each atom provides an electron and both of them share the two electrons. An example of this might be H2O where each hydrogen provides one electron, and oxygen provides one electron to make the O-H bond.
It will gain an electron so that it can complete a full outer shell of 8 electrons.
None - it would have to GAIN one.
It would gain or share an electron - in order to complete the outer shell.
Silver is a metal therefore it loses an electron when it reacts to form Ag+
Atom lose electron to form positive ion and some gain electron to form negative ion.
to become stable, it will gain an electron from a metallic atom otherwise it will mutually share electron(s) with another non - metallic atom, or even with itself
None, it is a noble gas.
As fluorine is a halogen (the group in which the elements are more reactive as they are one electron lesser than that of the octet configuration)and hence it can only gain electrons.
Share.
gain
Gain of one electron
gain
The elements in group 7A or 17, gain one electron during ionic bonding, or share one electron when undergoing covalent bonding.
