Metals because metals are mostly on the left side of the Periodic Table and have fewer electrons.
You are talking about an ionic bond. Take your regular table salt--NaCl. The sodium (Na) atom starts out with 11 electrons. The chlorine (Cl) has 17. Both want to be like their closest noble gas (Ne and Ar respectively). Thus, the Cl wants an extra electron, and Na wants to lose one. If you just want the answer with no explanation: Sodium is an element, but there are many. Google "ionic bond"

Alkali metals, alkaline-earth metals, and transition metals all will lose electrons
Anions typically loose an electron to form an ionic bond. Nucleophilic compounds or elements (Lewis bases) also loose electrons to form bonds.
Metals are the kinds of elements which lose electrons when forming bonds. Sodium, calcium, potassium, iron, and many more fall into this category.

Metal atoms
Silicon is an element in group 14. It has four valence electrons. Silicon tends to share electrons rather than releasing or obtaining four electrons (which needs tremendous energy). Hence it forms covalent bonds.
bonds
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
Sulphur has six valence electrons and hence it can form maximum of six covalent bonds as in SF6.
Valence electrons are used to form bonds. These are present in outermost shell.

Sodium is an alkali metal with 1 very reactive electron in its outer shell, it tends to form ionic bonds. Silicon is a semiconductor/pseudo-organic with 4 electrons in its outer shell, it tends to form covalent bonds. Sulfur is a non-metal with 6 electrons in its outer shell, it tends to like to borrow other atoms electrons but also forms covalent bonds.
nitrogen, it tends to form high energy bonds that are easily broken.
The valence electrons of an atom determine how the element forms chemical bonds with other elements to form chemical compounds.
Hydrogen, depending upon what element it is combining with, can act either as a metal or a nonmetal. But as a nonmetal it shares electrons in the form of covalent bonds, rather than actually donating them. Similarly, carbon can react with metals or nonmetals but forms covalent bonds. To truly donate or accept electrons is to form ionic bonds, and no element has the flexibility to form ionic bonds both as a donor and as an acceptor. Elements can do one or the other, if they form ionic bonds. Some elements only form covalent bonds.

YES!!!! Taking Sodium and Chlorine as an example. Sodium metal is an element. Chlorine gas is an element. Put them together in a gas jar and they will react to form the compound sodium chloride. In nature atmospheric nitrogen (an element) will react with atmospheric oxygen (also an element), when a lightning strike discharges, to form nitrogen oxides (compounds).
Valence electrons-electrons that are farthest from an atoms nucleus- are the electrons that form bonds with other atoms.
