Total questions: 15
Worksheet time: 8mins
Why is the Periodic Table called what it is?
because of the regularly repeating patterns in the properties of elements.
because there are columns and rows in the Periodic Table
because the elements are arranged in groups
because that is the first name that someone suggested
Mendeleev's periodic table left gaps for the...
elements that were metals
elements that were non-metals
unknown elements
The atomic number of an element determines...
....if it is non-metal or metal
...the number of electrons in the outermost shell
...its chemical properties
...its position in the periodic table
The number of electrons in the outermost shells of an atom determines...
...its chemical properties
...number of electrons
...positon in the period table
Why are noble gases, in group 0, unreactive?
they have very stable electron arrangements
because they exist as single atoms
they have low boiling points
Alkali metals - their melting and boiling points decrease ...
going down the group
going up the group
going across the group
Why are the alkali metals stored under oil?
to give the metal nutrients to keep it healthy
to stop them reacting with oxygen in the air
because they are so soft and easy to cut
to keep the shine in the metal
The metals react with water to produce...
ionic compounds
isotopes
hydrogen and an alkaline solution containing the metal hydrogen
atoms
The reactivity of the alkali metals increases...
going down the group
going up the group
Which group of the elements are called halogens?
Group 7
Group 3
Group 4
Group 5
What are halogens?
Noble gases
A group of toxic non-metals that have coloured vapours and have fairly typical properties of non-metals.
Covalent bonds
Non-alkali metals
The halogens all form covalent compounds by sharing...
electrons with other non-metals
ionic compounds with metals
electrons with another atom
The reactivity of the halogens decreases going...
up the group
down the group
Larger atoms lose electrons more easily going
down the group
up the group
across the group
Larger atoms gain electrons less easily going
down a group
across the group
up the group
