it should gain one electron
Atoms attain stable configuration of noble gas by gaining or losing electrons to achieve a full outer electron shell, often referred to as an octet. This stable arrangement mimics the electron configuration of noble gases and provides the atom with increased stability and lower energy. This can be achieved through ionization (loss or gain of electrons) or bonding with other atoms to share electrons.
They achieve noble gas configuration by the sharing of electrons.
Se has to gain two electrons
Noble gases have a full outer electron shell, making them stable and chemically inert. This arrangement gives them little tendency to gain, lose, or share electrons with other atoms, making them nonreactive under normal conditions.

As all chemical elements atoms noble gases contain protons, neutrons and electrons.
Atoms try to imitate the noble gases in the periodic table by changing their electrons. Noble gases have stable electron configurations, so other atoms will gain, lose, or share electrons in order to achieve a similar stable configuration like the noble gases.
1 electron
It should loose 2 electrons to become a noble gas.
Atoms lose or gain or share electrons and tend to attain noble gas configuration
Oxygen needs to gain 2 electrons to achieve a noble gas configuration, as it has 6 valence electrons and wants a full valence shell of 8 electrons, like a noble gas.
Atoms gain, lose or share electrons and try to attain noble gas configuration.
Selenium should gain two electrons and lose six electrons to achieve a noble gas electron configuration.
