How many electrons must beryllium gain or lose to form stable ions

Explanation:

beryllium must loss 2 electrons to form a stable octet to its nearest noble gas Helium.

It can loss electron because it is a metal and is placed in 2group and 2 period in group of alkaline earth metals.

hope this helps you to.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions
