Nonmetals and metals
Most of the nonmetals, particularly the halides.
2 nonmetals
calcium and lithium are both metals and dont form bond with each other. sodium and flourine form ionic compound, sodium fluoride. nitrogen and oxygen form covalent bond in the nitrogen oxides. helium and argon are both nonmetals / noble gases and dont form bond with each other.
Covalent bonds usually form between two nonmetals/
Phosphorous or nitrogen
Magnesium and sulfur are much more likely than nitrogen and oxygen to form an ionic bond, because the difference in electronegativity between sulfur and magnesium is much greater than the difference in electronegativity between nitrogen and oxygen. Another way of phrasing the reason is that magnesium is a metal and sulfur a nonmetal, while nitrogen and oxygen are both nonmetals.
Nonmetals and metals
Chlorine is the most reactive gas element. Chlorine is in the halogen family.
Most of the nonmetals, particularly the halides.

No, they are not likely to bond. Neon has a complete octet and is not reactive.
This indicates that the person who has antibodies reactive to the Hepatitis B or C virus and likely has been exposed to the disease (and likely has it).

False, a growing child is not likely to exhibit negative nitrogen balance.
Phosphorous is a multivalent nonmetal of the nitrogen group. It is found in nature in several allotropic forms, and is an essential element for the life of organisms.There are several forms of phosphorous, called white, red and black phosphorous, although the their colours are more likely to be slightly different. White phosphorous is the one manufactured industrial; it glows in the dark, is spontaneously flammable when exposed to air and is deadly poison. Red phosphorous can vary in colour from orange to purple, due to slight variations in its chemical structure. The third form, black phosphorous, is made under high pressure, looks like graphite and, like graphite, has the ability to conduct electricity.ApplicationsConcentrated phosphoric acids are used in fertilizers for agriculture and farm production. Phosphates are used for special glasses, sodium lamps, in steel production, in military applications (incendiary bombs, smoke screenings etc.), and in other applications as: pyrotechnics, pesticides, toothpaste, detergents.
