Hydrogen
Hydrogen
The element Hydrogen (H) has only 1 electron. When it loses it, it becomes the Ion H+.
Hydrogen.
There is no metal like you describe in your question. Hydrogen is in Group 1, but is not an alkali metal. It is a gas at standard temperature. It does rarely behave like an alkali metal, and it does have only one electron. Hydrogen is in Group 1 primarily because of its electron configuration, which is 1s1. All of the alkali metals also have one electron in their outermost s orbital.
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.
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.
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.
Alkali metals have 1 electron in their outer shell, which makes them highly reactive. They easily lose this electron to form positively charged ions, making them good reducing agents. This electron configuration and reactivity are key factors influencing the properties of alkali metals.
Hydrogen
here r the possisble answers: both atoms lose 1 electron a covalent bond forms metal gains an electron and the nonmetal loses an electron metal loses an electron and non metal gains an electron
Hydrogen, it is one of the most difficult elements to classify: it can form +1 ions like the alkali metals, it can form -1 ions like the halogens, it is a nonmetal.
1 valence electron. It is an alkali metal and all alkali metals have one atom on their last energy level.
