Hydrogen gas is evolved along with the formation of a salt.

For example, when hydrochloric acid (HCl) is reacted with magnesium (Mg):

2 HCl + Mg --> MgCl2 + H2

Metals that are chemically active have low electronegativity because matals have a weak attraction to electrons.

Alkali metals are the most reactive metals.

Noble gases are chemically inactive. the most active metals are found in group 1 (alkali metals)

Metals in group one are chemically active as compared to the elements in group three and two. Elements like sodium, potassium, chlorine and fluorine are some of the chemically active elements.

In the group 1: alkali metals - Li, K, Na, Cs, Rb, Fr.

Alkaline metals are usually found only as compounds in Nature because these metals are very active chemically and will combine with many commonly found substances such as water.

When dilute acids and metals are mixed you will get Hydrogen gas and salts

Alkali metals are very chemically reactive, are not dense or hard metals and have low melting points.

Nickel is one of the less chemically active metals. It does not easily combine with other elements.

Many metals including alkali metals, alkali earth metals, chromium, nickel and zinc react with dilute hydrochloric acid.

Highly active metals are the most easily oxidized because they react with oxygen easily.

Lots of metals will react with dilute hydrochloric acid; anything above hydrogen in the activity series should do so.

The most active metals are to the most left or the group 1 metals.

Cesium has a much higher energy content than silicon. It belongs to one of the most chemically active group of elements, the alkali metals, and in turn is one of the more active in that group.

Metals and nonmetals form ionic compounds when chemically bonded.

Alkali MetalsLithium, potassium and sodium are considered to be some of the most active metals.

No. Metals liberate hydrogen gas from acids.

For example metals as Pt, Au, Os and other.
