- Fc and d
- Gall of the above
2Henry Moseley is most known for fixing Dmitri Mendeleev's periodic table and rearranging them in order of ATOMIC NUMBER.
- ATrue

11As more energy levels are added to atoms, many more electrons can be held. The space between electrons and protons DECREASES. this is known as electron shielding
- ATrue
- BFalse
12Going [blank_start]left to right[blank_end] the atomic radius decreases because of nuclear charge. Going [blank_start]down[blank_end] the atomic radius increases because of electron shielding
- Aleft to right
- Bup
- Cright to left
- Ddown
- Eupwards
- Fhorizontally
13Radius is measured by taking half the distance between the nuclei of two atoms that are next to each other.
- ATrue
- BFalse
14In a cation
- Athe size is larger than a neutral element
- Bthe size is smaller than the a neutral element
15What is true about ionization energy
- AIt is the energy required to remove an electron from an atom
- Bthe IE of valence electrons will be much smaller than that of inner electrons
- Cit states that electrons will occupy lower energy levels first before filling in higher energy levels
- Dit increases from left to right and decreases from top to bottom
- Eit decreases from left to right and increases from top to bottom
- Fthere's a big jump
16Electronegativity is
- AThe ability of an atom to attract electrons towards itself.
- BThe amount of energy released when an electron is added to a neutral atom to form an anion.
- CtHE Energy required to remove an electron from an atom
17Electron affinity is
- AThe amount of energy released when an electron is added to a neutral atom to form an anion.
- BThe ability of an atom to attract electrons towards itself.
- CEnergy required to remove an electron from an atom
