Description
Question 1
Question
In the 19th century, did scientists know the structure of atoms?
Answer
- True
- False
Question 2
Question
In 1863, Newlands proposed his...
Answer
-
Law of octaves
-
Theory of evolution
-
Law of structures
Question 3
Question
What did the law of octaves state?
Answer
-
8 keys in a piano is an octave
-
Similar properties are repeated every 8th element
-
8 elements are a group
Question 4
Question
Why was Mendeleev's periodic table better than Newlands?
Answer
-
He left gaps for undiscovered elements
-
He discovered the missing elements
-
He discovered the structure of an atom
Question 5
Question
Elements are arranged in the periodic table in order of their atomic numbers
Answer
- True
- False
Question 6
Question
Why do elements in the same group have similar chemical properties?
Answer
-
They follow Newlands law of octaves
-
Their atoms have the same number of electrons in their outer shell
Question 7
Question
When metals react they lose electrons so...
Answer
-
The reactivity of metals in a group increases going down the group
-
The reactivity of metals in a group decreases going down the group
Question 8
Question
When non-metals react they gain electrons so the reactivity of non-metals decreases going down the group
Answer
- True
- False
Question 9
Question
Group 1 elements are called the...
Answer
-
Acid metals
-
Alkali metals
Question 10
Question
They react readily with...
Answer
-
Air and water
-
hydrogen
Question 11
Question
Alkali metals have low melting and boiling points that decrease going down the group
Answer
- True
- False
Question 12
Question
Alkali metals react with water to produce hydrogen gas and...
Answer
-
Oxygen
-
A metal hydroxide
Question 13
Question
Group 1 metals form ionic compounds in reactions
Answer
- True
- False
Question 14
Question
Why does reactivity increase going down group 1?
Answer
-
The outer electron is less strongly attracted to the nucleus as the number of shells increase and the atoms get larger
-
The outer electron is more strongly attracted to the nucleus as the number of shells increase and the atoms get larger
Question 15
Question
Transistion elements are...
Answer
-
Bad conductors of heat
-
Malleable, ductile and good conductors of heat
-
Not malleable and hard to bend
Question 16
Question
Do transition elements react slowly or quickly with oxygen and water?
Answer
-
Quickly
-
Slowly
Question 17
Question
Are transition elements useful as building materials?
Answer
-
No because they are weak
-
Yes because they are strong and dense
Question 18
Question
Compounds of transition elements are...
Answer
-
Dull colours
-
Brightly coloured
Question 19
Question
Transition elements form positive ions
Answer
- True
- False
Question 20
Question
Which group are the halogens?
Answer
-
Group 1
-
Group 4
-
Group 7
Question 21
Question
Fill in the gap: Fluorine is a ........................................... at room temperature
Answer
-
Pale yellow gas
-
Yellow solid
Question 22
Question
Chlorine is a green gas at room temperature
Answer
- True
- False
Question 23
Question
Bromine is a green liquid at room temperature
Answer
- True
- False
Question 24
Question
Iodine is a grey solid at room temperature that easily vapourises to a violet gas
Answer
- True
- False
Question 25
Question
How do halogens bond with metals and non-metals?
Answer
-
Metals: Form an ionic compound Non-metals: Bond covalently to form molecules
-
Metals: They don't bond with Non-metals: Form an ionic compound
Question 26
Question
Why does the reactivity of the halogens decrease going down group 7?
Answer
-
The attraction of the outer electrons to the nucleus increases as the number of occupied shells increase
-
The attraction of the outer electrons to the nucleus decreases as the number of occupied shells increase
