1 punto A) poseen electronegatividad igual o semejante. B) poseen electronegatividad muy diferente. C) transfieren electrones entre sí. D) se ubican en grupos lejanos entre sí en la tabla periódica. E) ceden electrones.

first one is the correct answer

1 a

2 d

3 a

4 c

explanation:

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
