Atoms-Tiny particles of matter that cannot be divided
Answer:
neon is the Noble gas but I have not studied this much
Be and B: Be is 1s2 2s2 and B is 1s2 2s2 2p1
Be has full 2 orbitals and so does B but B only has 1 electron in p so it is really unstable and easy to react. So there is a dip in ionization energies. The other questions are similar to this so if you need, feel free to ask me
