The non metals. (this ignores the special case of transition metals see the linked answer for info. on this topic.)
non metal..ight
It is a metal.
no only metals
Yes
Carbon.
No
They are called valence electrons. Ionic is a bond between a nonmetal and a metal. A covalent bond(molecular bond) is between two or more non metals.
When a metal reacts with a non-metal, the electrons move from the metal to the non-metal. This is because the metal can achieve valence when it loses the electrons in its outer shell. The non-metal can also achieve full valence by gaining the electron in its outer shell.
The question is worded badly so I'll give the answer to two difrent questions. A group of two or more atoms bonded together to form a covalent bond is a molecule. But if there are far more, where the molecule gets ectremely complex, it's called a polymer. The reason WHY they form a covalent bond would be because they're a metal & a nonmetal. Metals have less than 5 valence electrons so therefor they want to lose electrons. Whereas a non-metal has more then 5 valence electrons so it wants to GAIN electrons. So for them to both have full outer shells the metal(s) will give the non-metal(s) their valence electrons, createing a covalent bond.
yes it does. if the electrons are lost easily, reactivity is more.
Elemental oxygen is found as a diatomic gas O2 or the reactive triatomic gas O3 rather than as a metal. Chemically it is considered to be a non metal as it forms ionic compounds with many metals. Oxygen has 6 valence electrons and has to 'gain' two more electrons to be stable.
ions are formed based upon the valence electrons of the element and if the element is a metal or a nonmetal. S has 6 valence electrons and needs 2 more to be stable. it is a nonmetal. therefore, taking on 2 electrons gives S a -2 charge
They are called valence electrons. Ionic is a bond between a nonmetal and a metal. A covalent bond(molecular bond) is between two or more non metals.
The outer electrons of a metal atom that bonds with a nonmetal atom are either transferred to the nonmetal to form an ionic bond or shared with the nonmetal to form one or more covalent bonds.
No. If the reaction described occurs at all, it would form a covalent coordinate bond.
A metal in the alkali metal family has one valence electron where as a metal in boron family has three valence electrons. It is easy to remove one valence electrons than three. So alkali metals will be more reactive.
Yes. Metals have lower electronegativities than nonmetals, and they tend to have fewer than four valence electrons, so they are more likely to lose electrons in order to achieve a noble gas configuration and become stable.

According to my chem book, a transfer of one or more electrons from the metal to the nonmetal often occurs

A reactive non metal is an element that can gain the electrons or is more electronegative
