2Who created the law of octaves for ordering elements?
- AMendeleev
- BDalton
- CNewlands
3Who created the modern periodic table?
- AMendeleev
- BDalton
- CNewlands
4True or false? The reason why Mendeleev's periodic table worked was because he left gaps for undiscovered elements which may have had similar properties.
- AVerdadero
- BFalso
5What is unusual about the pair of elements tellurium (Te, Z = 52) and iodine (I, Z = 53)?
- ATellurium has similar properties to the halogens and is placed with them, while iodine has similar properties to Group 6 and is placed with them
- BTellurium has a higher relative atomic mass than iodine
- CTellurium has 7 outer electrons although it is placed in Group 6, and iodine has 6 outer electrons but is placed in Group 7
6True or false? In the modern periodic table, elements are arranged by mass number.
- AVerdadero
- BFalso
7True or false? Larger atoms lose electrons more easily and gain electrons less easily than smaller atoms.
- AVerdadero
- BFalso
8Which of these are the most reactive in their respective groups?
- APotassium, Group 1
