Answer from: u8p4

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.

Answer from: jaimefashion12

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.

Across a period, electronegativity increases from left to right. Down a group, it decreases.

In group 2, the electronegativity decreases downward.

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
