Simple Chemistry Questions?? help please?
(1) Lithium has atomic number 3 and atomic mass 7
is it an electron acceptor?
(2) Beryllium has atomic number 4 and atomic mass 9
Is it stable, neutral, both, or neither?
(3) KBr ----> K+ + Br-. Therefore KBr is a(n):
acid
base
salt
none
Answer:
1) Li is an electron donor : Li >> Li+ + 1e-
2 ) Be is stable
3) KBr is a salt
1) no it pretty much donates its electron
2) both
3) salt
stable, salt
1) Lithium is an electron donator. It gives up 1 to have a full valence shell of 2.
2) Stable, but not neutral.
3) KBr (Potassium bromide) is a salt. Any ionic compound is a salt.
