Select one of the following:

  • True
  • False

Explanation

Question 2 of 26

1

In 1863, Newlands proposed his...

Select one of the following:

  • Law of octaves

  • Theory of evolution

  • Law of structures

Explanation

Question 3 of 26

1

What did the law of octaves state?

Select one of the following:

  • 8 keys in a piano is an octave

  • Similar properties are repeated every 8th element

  • 8 elements are a group

Explanation

Question 4 of 26

1

Why was Mendeleev's periodic table better than Newlands?

Select one of the following:

  • He left gaps for undiscovered elements

  • He discovered the missing elements

  • He discovered the structure of an atom

Explanation

Question 5 of 26

1

Elements are arranged in the periodic table in order of their atomic numbers

Select one of the following:

  • True
  • False

Explanation

Question 6 of 26

1

Why do elements in the same group have similar chemical properties?

Select one of the following:

  • They follow Newlands law of octaves

  • Their atoms have the same number of electrons in their outer shell

Explanation

Question 7 of 26

1

When metals react they lose electrons so...

Select one of the following:

  • The reactivity of metals in a group increases going down the group

  • The reactivity of metals in a group decreases going down the group

Explanation

Question 8 of 26

1

When non-metals react they gain electrons so the reactivity of non-metals decreases going down the group

Select one of the following:

  • True
  • False

Explanation

Question 9 of 26

1

Group 1 elements are called the...

Select one of the following:

  • Acid metals

  • Alkali metals

Explanation

Question 10 of 26

1

They react readily with...

Select one of the following:

  • Air and water

  • hydrogen

Explanation

Question 11 of 26

1

Alkali metals have low melting and boiling points that decrease going down the group

Select one of the following:

  • True
  • False

Explanation

Question 12 of 26

1

Alkali metals react with water to produce hydrogen gas and...

Select one of the following:

  • Oxygen

  • A metal hydroxide

Explanation

Question 13 of 26

1

Group 1 metals form ionic compounds in reactions

Select one of the following:

  • True
  • False

Explanation

Question 14 of 26

1

Why does reactivity increase going down group 1?

Select one of the following:

  • 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

Explanation

Question 15 of 26

1

Transistion elements are...

Select one of the following:

  • Bad conductors of heat

  • Malleable, ductile and good conductors of heat

  • Not malleable and hard to bend

Explanation

Question 16 of 26

1

Do transition elements react slowly or quickly with oxygen and water?

Select one of the following:

  • Quickly

  • Slowly

Explanation

Question 17 of 26

1

Are transition elements useful as building materials?

Select one of the following:

  • No because they are weak

  • Yes because they are strong and dense

Explanation

Question 18 of 26

1

Compounds of transition elements are...

Select one of the following:

  • Dull colours

  • Brightly coloured

Explanation

Question 19 of 26

1

Select one of the following:

  • True
  • False

Explanation

Select one of the following:

  • True
  • False

Explanation

Question 25 of 26

1

How do halogens bond with metals and non-metals?

Select one of the following:

  • Metals: Form an ionic compound
    Non-metals: Bond covalently to form molecules

  • Metals: They don't bond with
    Non-metals: Form an ionic compound

Explanation

Question 26 of 26

1

Why does the reactivity of the halogens decrease going down group 7?

Select one of the following:

  • 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
