atoms = smallest unit of an element
elements = contain only one type of atom
compounds = two or more elements that are chemically bound together
molecules = a group of atoms bonded together
I just learned this myself and it was sort of confusing to me. Inbox me and I'll do my best to explain it.
The answer is 8. atomic number: the number of protons in the nucleus of an atom.
Answer:
Cl
Explanation:
The element Cl will have the strongest ionization energy from the given choices. Most non-metals have higher ionization energy compared to metals.
Ionization energy is the energy required to remove the most loosely held electron from the gaseous phase of an atom.
- As you go from left to right on the periodic table, it increases progressive
- From top to bottom, the ionization energy reduces significantly.
- The attractive force between the protons in the nucleus and the electrons plays a very important role.
- In metals, they have very large atomic radius, the attractive force on the outer electrons is very weak.
- This is not the case in non-metals
