the element would be Iodine (I) bc it has 53 protons
It's 2) a positively-charged nucleus is surrounded by mostly empty space (aka Rutherford's Model).
Most of the atom's mass is inside the nucleus (which contains protons [+] and neutrons [0 charge]), while the electrons [-] "float" around the nucleus like clouds. This is why it's said that the atom is 'mostly empty space'.
I think you forgot to add some of the question
Answer:
Solubility is determined by the molecular or ionic structures of the solute and the solvent, and by the intermolecular forces that hold together the particles of each substance
Explanation:
- Ionic bonds and covalent bonds are sort of intermolecular forces
-State of matter does not hold together the particles of each substance
<span>A metal is one which ionizes easily and gives electrons whencompared to other elements.
So it should have a lower ionization energy.
Hence we would expect element 2 to be a metal.</span>
