1In the 19th century, did scientists know the structure of atoms?
- AVerdadero
- BFalso
2In 1863, Newlands proposed his...
- ALaw of octaves
- BTheory of evolution
- CLaw of structures
3What did the law of octaves state?
- A8 keys in a piano is an octave
- BSimilar properties are repeated every 8th element
- C8 elements are a group
4Why was Mendeleev's periodic table better than Newlands?
- AHe left gaps for undiscovered elements
- BHe discovered the missing elements
- CHe discovered the structure of an atom
5Elements are arranged in the periodic table in order of their atomic numbers
- AVerdadero
- BFalso
6Why do elements in the same group have similar chemical properties?
- AThey follow Newlands law of octaves
- BTheir atoms have the same number of electrons in their outer shell
7When metals react they lose electrons so...
- AThe reactivity of metals in a group increases going down the group
- BThe reactivity of metals in a group decreases going down the group
8When non-metals react they gain electrons so the reactivity of non-metals decreases going down the group
- AVerdadero
- BFalso
9Group 1 elements are called the...
- AAcid metals
- BAlkali metals
10They react readily with...
- AAir and water
- Bhydrogen
11Alkali metals have low melting and boiling points that decrease going down the group
- AVerdadero
- BFalso
12Alkali metals react with water to produce hydrogen gas and...
- AOxygen
- BA metal hydroxide
13Group 1 metals form ionic compounds in reactions
- AVerdadero
- BFalso
14Why does reactivity increase going down group 1?
- AThe outer electron is less strongly attracted to the nucleus as the number of shells increase and the atoms get larger
- BThe outer electron is more strongly attracted to the nucleus as the number of shells increase and the atoms get larger
15Transistion elements are...
- ABad conductors of heat
- BMalleable, ductile and good conductors of heat
- CNot malleable and hard to bend
16Do transition elements react slowly or quickly with oxygen and water?
- AQuickly
- BSlowly
17Are transition elements useful as building materials?
- ANo because they are weak
- BYes because they are strong and dense
18Compounds of transition elements are...

- BYellow solid
22Chlorine is a green gas at room temperature
- AVerdadero
- BFalso
23Bromine is a green liquid at room temperature
- AVerdadero
- BFalso
24Iodine is a grey solid at room temperature that easily vapourises to a violet gas
- AVerdadero
- BFalso
25How do halogens bond with metals and non-metals?
- AMetals: Form an ionic compound
Non-metals: Bond covalently to form molecules - BMetals: They don't bond with
Non-metals: Form an ionic compound
- AMetals: Form an ionic compound
26Why does the reactivity of the halogens decrease going down group 7?
- AThe attraction of the outer electrons to the nucleus increases as the number of occupied shells increase
- BThe attraction of the outer electrons to the nucleus decreases as the number of occupied shells increase
