Yr 11 Transition Reflection Quiz

The vertical columns in the periodic table are called

• periods

• groups

• metals and non metals

• they don't have a name

Periods can be found

• As rows in the periodic table going across

• on your school timetable (nothing to do with chemistry)

• as columns in the periodic table

Elements that react in a similar way are found in

• The same period as they have the same amount of shells

• The same group as they have the same amount of shells

• The same period as they have the same amount of valence shell electrons

• The same group as they have the same amount of valence shell electrons

Effective nuclear charge

• is that the same for all elements in the same group

• is the same for all elements in the same period

• decreases from left to right across a period

• increases as you go down a group

Atomic radius

• increases as you go across a period

• decreases as you go down a group

• decreases as you go across the period

• stays the same as you go across the period as the amount of shells don't change

Electronegativity

• Is the ability for an atom to lose an electron from its outer shell when forming a chemical bond

• the ability of an atom to attract electrons towards itself when forming a chemical bond

• how charged particle interact

• will be the highest for metals

First Ionisation energy

• Increases as you go down a group

• Decreases as you go from left to right across the period

• Is the ability for an atom to attract an electron towards itself

• the energy needed to remove one electron from an atom of the element

A covalent bond will be found between

• the atoms of hydrogen and oxygen in a water molecule

• the atoms of sodium and chlorine

• between molecules of water

• You can not answer this question with the information given

An example of an ionic compound is

• CH4

• MgO

• H2O

• H2
