Year 10 Atomic Structure and The Periodic Table

1.     All matter in the universe is made of extremely small particles called:

• Elements

• Compounds

• Protons

• Atoms

Which statement is true about the atomic mass of an element on the periodic table?

• It tells us the number of protons plus electrons of an element

• It tells us the number of protons plus neutrons of an element

• It tells us the valency of an element

• It tells us only the number of electrons of an element

Which particles make up the nucleus of an atom?

• Protons and Electrons

• Neutrons and Protons

• Electrons and Neutrons

• None of these

Ionic bonding between two elements only occurs between:

• Metal and non-metal elements

• Only metal elements

• Only non-metal elements

• Positively charged elements

The periodic table lists the elements…

• In order of their atomic mass

• In order of their number of protons

• In order of increasing reactivity

• In no particular order

A characteristic property of any group 18 (simplified group 0) element is that they are all:

• Stable

• Highly reactive

• Behave as metals

• All answers are correct

True or False: All isotopes of an element have the same number of protons

• True

• False

True or False: A positive ion is an element that has lost one or more protons

• True

• False

True or False: Halogens are located in group 16 (simplified group 6) on the periodic table

• True

• False

True or False: Group 18 (simplified group 0) elements include noble gases

• True

• False
