Describe the general trend in electronegativity as the metals in Group 2 on the Periodic Table are considered in order of increasing atomic number.

Electronegativity is the ability of an atom to attract the electrons to form a covalent.

The general trend of electronegativity increases across the periods and groups.

The trend of electronegativity of Group 2 can be explained as:

1. In group 2, the electronegativity varies with the increase in the atomic number of the elements. The electronegativity decreases as the atomic number increases.

2. The electronegativity increases because the outer electrons are shielded due to the strong attraction of the nucleus.

3. The highest electronegative element of Group 2 is Be, and the least is Barium.

Thus, the electronegativity decreases down the group with an increase in the atomic number.

It decreases down the group

Explanation:

In group 2 of the periodic table, the value of the electronegativity decreases as we go down the group.

Electronegativity of an element is a property that combines the ability of its atom to lose and gain electrons.

It is a measure of the relative tendency with which atoms of the element attracts valence electrons.

In group 2, the electronegativity decreases downward.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
