The ion given is formed when the neutral arsenic atom gains three electrons.
No. Atoms can gain and lose electrons but seldom gain or lose protons.
gain
Atomic number of arsenic is 33 so that would leave you with 36 electrons
Gain or lose
If the chemical bond is ionic, an electron is gained or lost. If it is covalent, the electron is shared equally; if it is polar covalent, the electron is shared unequally. If the bond is intermolecular, no parts of the atom are actually shared, gained, or lost; the atom itself is simply attracted to other atoms.
No. Atoms can gain and lose electrons but seldom gain or lose protons.
Covalent bonds do not gain or lose electrons, but rather share electrons.
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.
Lose
When atoms lose or gain electrons, they form ions. These are charged particles.
Se will gain electrons
In phosphene it gain 4 electrons. Phosphate lose 4 electrons
Lose electrons is oxidation. To gain electrons is reduction.
If you mean Metals... No, they do not gain electrons, they actually lose electrons because it is a lot easy for them to lose them so they can gain stability much faster.
Polonium lose electrons.
sn lose 4 electrons
Sodium lose electrons becoming a cation.
