How many protons and electrons are present does the ion Li+ have?

is it 38 because i remember it was with 30 something

2

Explanation:

Electron config of lithium = [He] 2s1 or 1s2 2s1

For Li to form it's cation, it has to lose a single electron from it's outermost shell

So, 1s2 2s1 becomes 1s2 as it loses that outer shell 2s1  electron to form the cation

So it's left with 2 electrons in it's 1s shell.

Answer = 2

alchemy hadn't scientific methods of study, appeal to mysticism and fantasy, the knowledge of chemistry and physics were modest at that time.

alchemy was - but as new rules were discovered it either changed into chemistry or it became "unscientific".
