Hydrogen.
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
they all have one valence electron.
An alkali metal has 1 valence electron. Group 1 elements, such as lithium, sodium, and potassium, all have 1 valence electron in their outermost energy level.
When a group 1 metal atom loses an electron, it becomes a positively charged ion, known as a cation. This process results in the formation of a stable electron configuration, often resembling that of a noble gas. The loss of the electron also makes the atom smaller due to decreased electron-electron repulsion. Consequently, group 1 metals are highly reactive and readily form ionic compounds with nonmetals.
If its mass is 0.6 g and its volume is 1 cm3 , then its density is 0.6 g per cm3 .
It only floats if the density of the metal used is less than 1 gm/cm3
Hydrogen has 1 electron. It can easily gain or lose electron to form metal or non metal
Specific gravity refers to the ratio of the density of a substance to the density of a standard, which is usually water. A piece of metal that has a mass of 200 g and a volume of 2 cm3 has a specific gravity of 100.
Specific gravity is the ratio of the density of a substance to the density of water. To calculate it, you first need to find the density of the metal by dividing its mass (200 g) by its volume (40 cm3), which equals 5 g/cm3. The density of water at 4 degrees Celsius is 1 g/cm3, so the specific gravity of the metal is 5.

The density of the metal is 11.33 g/cm3. This is calculated by dividing the mass (68g) by the volume (6 cm3).
It depends on the density of the metal.
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
A cesium atom has 1 valence electron. It is an alkali metal, and all alkali metals have 1 valence electron. The electron configuration for cesium is (Rn)7s1. The single electron in the 7s sublevel is its valence electron.
Density of uranium: 19,1 g/cm3 1 cubic inch = 16,38706 cm3 The mass of 1 cubic inch of uranium is 313 g.
