Elements with a high electronegativity are usually electron acceptors. in other words, they have valence shells that are almost full. which of the following elements would have the lowest electronegativity? a. agb. fec. crd. ca

Ca

Explanation:

As a general trend on the periodic table, the electronegativities of elements decrease down the group and increase across the periods. Since calcium is in group two , it is expected to have the lowest amount of electronegativity due to its specific location on the periodic table.

To show that this prediction is true, I will write the elecronegativity values of these atoms. Calcium has a value 1.0, Silver 1.93 , Iron 1.83 and chromium 1.66

d.) gravity pulled particles of dust and gas together to form planets.
