Which of the following atoms typically
form negative ions?
(a) f (b) li (c) ne (d) s (e) al (f) be

Good Question

see Negative ions are those which gain electrons to attain stability

Now, We know All metals tend to donate electrons which inturn results in positive charge

Now Have a closer look at options

a) F

It is fluorine

it's configuration is 2,7

that means it requires one electron to complete it's octet from 7 to 8

therefore, it will gain one electron which results in

b)Li

lithium is metal having one electron in outermost shell So it will rather loose electron to attain stability

c)Ne

Neon is Noble gas which exists in neutral stare

d)S

Sulphur needs 2 more electrons to attain stability

therefore it exists as negative ion

e)Al

Aluminum is metal So it exists as positive ion

f)Be also exists as positive ion

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.
