NO.
Nonmetals tend to GAIN electrons to complete their outer shell. By gaining electrons, they become a negatively charged species, which is what an anion is. Metals tend to LOSE electrons to end up with a full outer shell; in losing electrons, they develop a positive charge (become cations).
The electron configuration of oxygen is [He]2s22p4.
The electrons configuration for O2- is [He]2s22p6.
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
Mg 2+ Has the same electron configuration as neon. Two electrons lost to do this.
The electron configuration for an atom of fluorine is [He]2s2.2p5.
Electron configuration for an atom is the distribution of electrons on atomic orbitals.
electron configuration :)
The electron configuration of oxygen is [He]2s22p4.
The arrangement of the electrons in an atom is known as its electron configuration.
The electron configuration of sulfur is [Ne) 3s2.3p4.
The electrons configuration for O2- is [He]2s22p6.
No. They gain electrons
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.

Two electrons
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
For example metals loss electrons and nonmetals gain electrons.
