Suppose you discovered a new element with 120 protons and 2 electrons in its outer lever. In what group does this new element belong

Assuming the 2 valence electrons are of the neutral state of the new element, the element would belong in Group 2, the Alkaline Earth Metals.

This new element belongs to the group 2.

Explanation:

In the periodic table, the vertical columns are called groups (or families). The elements in the same group share similar chemical and physical properties.

One of these properties is the same amount of outer valence electrons.

For example, in the group 1 the elements have 1 outer valence electron (If we assume that the element is in a neutral state which is without electrical charges).

If this new element has 2 electrons in its outer level it will belong to the group 2. The group 2 is well-known as alkaline earth metals.

For example, the magnesium (Mg) and the calcium (Ca) belong to the group 2.
