Gaining and Losing Electrons. Next, let's review two atomic properties important to bonding that are related to the position of the element on the periodic table. They are the tendency or ability of atoms to lose electrons and the tendency or ability to gain electrons. First, let's consider the ability to lose electrons.


But in a solid or gaseous compound it does not actually gain any electrons. It actually only gains an electron when the bond is broken and the electrons go with the more electronegative bromine atom. ===== Follow up ===== All this "more stable" stuff is a bit misleading.


Nitrogen does not lose or gain electrons. It is a diatomic molecule (N 2) and is a molecular compound which has covalent bonding. In other words, the molecule has a triple bond, in which 6 ...


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.


Atoms gain or lose electrons based on their respective electron affinity. The greater the electron affinity of an atom, the more likely that atom is to accept an electron. Electron affinity changes based on the group of elements to which an atom belongs.

Due to the process of chemical bonding. Why does chemical bonding occur? So atoms or elements, when they exist as ions, they want to lose/gain or share electrons to attain a stable electronic configuration and achieve an octet/duplet valence shell structure resembling that of noble gases.


Section One. STUDY. PLAY. How can you determine the number of valence electrons in an atom of a representative element? To find the number of valence electrons in an atom of a representative element, simply look at its group number. ... How many electrons will oxygen gain or lose in forming an ion? O²⁻ ...


You are most likely expected to assume the element will "fill the octet" - that is, it will either lose or gain electrons till it has an octet on the outermost shell. That's only an approximation, and a poor one, of what can really happen in reality.


Atoms, Bonding, and the Periodic Table. STUDY. PLAY. What is the relationship or pattern between the number of energy levels an element has and the period it is in? ... Does Group 2 lose or gain how many electrons? Lose 2 electrons. Does Group 13 lose or gain how many electrons? Lose 3 electrons.
