Yes, because anions are always bigger than the atom in its ground state. Cations are smaller
O2, because it have more electrons than N2
O, O2-, S2-, and Se2-O is smaller than O2- because O2- has 2 extra electrons but the same amount of protons as O, so they are held less tightly and the atom is bigger. Atom size increases as you move down the periodic table, so O2- < S2- < Se2-.
O to the negative 2
O is an atom, but O2 is a molecule.
O2 (o=o)
O2, because it have more electrons than N2
O, O2-, S2-, and Se2-O is smaller than O2- because O2- has 2 extra electrons but the same amount of protons as O, so they are held less tightly and the atom is bigger. Atom size increases as you move down the periodic table, so O2- < S2- < Se2-.
O=oxygen atom, o2=oxygen molecule, o2-=oxide, o22-=peroxide, o2-=superoxide, o3=ozone.
O to the negative 2
O is an atom, but O2 is a molecule.
4Na + O2 --> 2Na2 + O
O is an atom, but O2 is a molecule.
0 is larger than -2.
O2 (o=o)
O
O2
it is a diatomic which makes it O2 and it has -2 charge
