Valence Electrons and Molecular Geometry

How many valence electrons does hydrogen have?

Answer explanation

Hydrogen has 1 valence electron. It is the first element in the periodic table and has an atomic number of 1, indicating it has one electron in its outer shell.

How many valence electrons does lithium have?

Answer explanation

Lithium (Li) is in group 1 of the periodic table, which means it has 1 valence electron. This is because valence electrons are determined by the group number for main group elements.

How many valence electrons does sodium have?

Answer explanation

Sodium (Na) is in group 1 of the periodic table, which means it has 1 valence electron. This is important for its chemical reactivity and bonding behavior.

How many valence electrons does potassium have?

Answer explanation

Potassium (K) is in group 1 of the periodic table, which means it has 1 valence electron. This is characteristic of alkali metals, which typically have one electron in their outermost shell.

How many valence electrons does rubidium have?

Answer explanation

Rubidium (Rb) is in group 1 of the periodic table, which means it has 1 valence electron. This is characteristic of alkali metals, which typically have one electron in their outermost shell.

How many valence electrons does cesium have?

Answer explanation

Cesium (Cs) is in group 1 of the periodic table, which means it has 1 valence electron. This is characteristic of alkali metals, which typically have one electron in their outermost shell.

How many valence electrons does francium have?

Answer explanation

Francium (Fr) is in Group 1 of the periodic table, which means it has 1 valence electron. This is characteristic of alkali metals, making the answer 1.

How many valence electrons does beryllium have?

Answer explanation

Beryllium (Be) is in group 2 of the periodic table, which means it has 2 valence electrons. These electrons are involved in chemical bonding.

How many valence electrons does magnesium have?

Answer explanation

Magnesium (Mg) is in group 2 of the periodic table, which means it has 2 valence electrons. These are the electrons in the outermost shell that participate in chemical bonding.

How many valence electrons does calcium have?

Answer explanation

Calcium (Ca) is in group 2 of the periodic table, which means it has 2 valence electrons. These are the electrons in the outermost shell that participate in chemical bonding.
