1What is Dmitri Mendeleev known for?
- AKnown as "the father of the periodic table"
- Bthe creation of periodic law
- Cthe law of triads
- Dthe law of octaves
- Ea and b
- 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.
- AVerdadero
- BFalso
3Periods are [blank_start]horizontal[blank_end] on the periodic table while groups are [blank_start]vertical[blank_end]
- Ahorizontal
- Bvertica;
- Cstraight
- Dsideways
- Evertical
- Fhorizontal
- Gacross
- Hsideways
4some properties of metals are...
- Ashiny, malleable, ductile, conducts heat and electricity
- BDull, brittle , not good conductors of heat and electricity, good insulators, usually gasses
- Csemiconductors
5[blank_start]Alkali metals[blank_end] are found in group [blank_start]1[blank_end] periods [blank_start]2-7[blank_end] of the periodic table and are very reactive in [blank_start]air and water[blank_end]

- H3
- I2-7
- J3-8
- K1-4
- L5-8
- Mair and water
- Nair and fire
- Ofire and carbon
- Poxygen and hydrogen
6One reason trends occur is because nuclear charge [blank_start]increases[blank_end] as protons [blank_start]increase[blank_end]
- Aincreases
- Bincrease

10[blank_start]Transitional metals[blank_end] are located in groups 4-12 and periods 4-7 while [blank_start]inner transition metals[blank_end] are located in the two bottom rows
- ATransitional metals
- Binner transition metals
- Cinner transition metals
- Dtransitional metals
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
- AVerdadero
- BFalso
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.
- AVerdadero
- BFalso
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
