Arsenic can lose and gain electrons.
Covalent bonds do not gain or lose electrons, but rather share electrons.
Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6
they share electrons
Atoms in the oxygen family can gain or share two electrons in order to achieve an octet of electrons.
it must gain (or share) two electrons
Oxygen will bond (share electrons) with other atoms to produce stable compounds ex. H2O ,O2
nitrogen
Oxygen is an oxidizer, it will gain electrons in a reaction to complete it's valence shell.
Oxygen molecules tend to prefer covalent bonding when forming compounds. This means that they will share electrons more readily. However, when forming an ionic compound, they will usually gain electrons rather than losing them.
carbon
it is in the oxygen family and has 6 valence electrons it requires 2 electrons
Arsenic can lose and gain electrons.
Covalent bonds do not gain or lose electrons, but rather share electrons.
Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
