To ensure that elements with similar properties stayed in the same groups. The gaps
Why did Mendeleev leave gaps in his
indicated the existence of undiscovered elements and allowed Mendeleev to predict
Table of Elements?
what their properties might be
How are the group number and the The group number tells you how many electrons are in the outer shell of an element.
number of electrons in the outer shell of an E.g. sodium is in Group 1 therefore it has 1 electron on its outer shell
element related?
What kind of ions do metals form? Positive
Where are the non-metals on the periodic On the right hand side
table?
1) They can form more than one ion e.g cobalt form Co2+
2)They are often coloured, therefore compounds which contain them are colourful
Give three properties which are specific to
e.g. potassium chromate is yellow
transition metals
3) They often make good catalysts e.g. nickel based catalysts are used in the
hydrogenation of alkenes
1) Increased reactivity - the outer electron is more easily lost as the
attraction between the nucleus and the electron decreases because the
State three trends as you go down Group 1 electron is further away from the nucleus
2)Lower melting and boiling points
3) Higher relative atomic mass
What are the products of the reaction of a Hydrogen gas and a metal hydroxide
Group 1 metal and water E.g. sodium + water --> sodium hydroxide + hydrogen
What's the difference between the Transition metals are harder, denser and stronger than Group 1 metals
hardness of Group 1 and transition metals?
What's the difference between the Group 1 metals are much more reactive than transition metals
reactivity of Group 1 and transition metals?
What's the difference between the melting Transition metals have higher melting points than Group 1 metals
points of Group 1 and transition metals?
1) They become less reactive - it's harder to gain an extra electron because the
What trends occur as you go down outer shell's further from the nucleus
Group 7? 2)They have higher melting and boiling points
3)They have higher relative atomic masses
What is the charge of the ions that They form negative ions
halogens form when they react with
metals?
What is the trend in boiling point as you go The boiling points increase
down Group 0?
What subatomic particles does the nucleus Protons and neutrons
contain?
What is relative atomic mass? The mass number which refers to the element as a whole
How are positive ions formed? A metal atom loses electrons
How are negative ions formed? A non-metal gains electrons
What is air a mixture of? Gases, mainly nitrogen, oxygen, carbon dioxide and argon
What is crude oil a mixture of? Different length hydrocarbon molecules
How can you separate substances in a Chromatography
mixture?
