Question

The following neutral atoms each have 8 places for electrons in their outermost shells.

Which atom will tend to lose rather than gain 1 or more valence electrons when forming an ion?

a. Li with 1 valence electron
b. O with 6 valence electrons
c. Ne with 8 valence electrons
d. F with 7 valence electrons

Answer 1

c. ne with 8 valenc3 electrons

Answer 2

Answer:

a. Li with 1 valence electron

Explanation:

For this it is necessary to see the electronegativity of this atoms. The electronegativity is the force or tendency that has an atom to attract electrons, so the atom who has the lower value of electronegativity is the one that will tend to lose rather than gain electrons.

The electronegativity of these atoms is:

Li – 0.98

O – 3.44

F – 3.98

Ne is a noble gas so has no tendency to gain nor lose electrons
