Answer 1

hello

Answer:

A) as electronegativity increases from left to right across a period we get higher values as we move from left to right

B) the atomic radii increases from top to bottom across a group

hence across F Cl Br A I it increases

I hope u understood

good day

Answer 2

Answer:

The ability of covalently bonded atom to attract the shared electron toward itself is called electronegativity.

The trend in electronegativity across the period:

As we move from left to right across the period

1. Atomic number increases

2.No. of shell are constant

3.sheilding effect is constant

4.Electron nuclear charge increases

5. Atomic size decreases

6. Tendency to attract shared pair of electron increases

7. Electronegativity increases
