Resource summary

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
