Topic 1: Success Criteria
Topic 1: Success Criteria
By the end of this topic you should know how to:
Classify the elements in the Periodic Table into: Solids, Liquids, Gases, Metal/Non-metal, man-made and natural.
Describe the structure of the Periodic Table using the terms: periods and groups accurately.
Identify the Group Numbers from left to right (1 to 8) and the Period Numbers 1 to 7 on the Periodic Table.
State that elements within the same group show similar chemical properties.
Correctly identify the following families of elements on a Periodic Table: halogens, alkali metals, alkaline earth metals, noble gases and transition metals.
Describe the atom as containing: positive protons, negative electrons and neutral neutrons.
State that the mass and charge of protons, electrons and neutrons as:
P: 1amu / positive
E: 0 amu / negative
N: 1amu / neutral
State that the atomic number of an element can used to identify it on the Periodic Table and is equal to the number of protons in an atom of that element.
State that all atoms are neutral because the number of Protons = the number of Electrons
State that the Mass Number of an atom is equal to the number of protons + number of neutrons.
Correctly describe an element in the correct format i.e. nuclide notation - see your notes for an example of this
Calculate the no. of neutrons in an atom using the subtraction: mass number – atomic number.
Recognise the electron arrangements of the first 20 elements.
Arrange the first twenty elements electrons into their specific energy levels.
Recognise the regularity of the Periodic Table.
Recognise that the elements with the same number of outer electrons are situated within the same group and have similar chemical properties.
Recognise that atoms of the same element can be different due to a slightly differing mass number.
State the meaning of positive ions and negative Ions in terms of the loss or gain of electrons.
State that atoms of the same element can be different due to a slightly differing Mass Number and that most elements are a mixture of isotopes
State what is meant by relative atomic mass (RAM) and understand how the RAM of an element can be calculated.
Be able to write the electron arrangement for the first 20 elements.
Correctly describe the meaning of valency.
Using valency numbers, be able to carry out formula using the cross over rule.
Be able to produce formula from transition metal valencies and ions containing more than one type of element (e.g. phosphate, chromate and nitrate).
State the meaning of isotopes.
State the meaning of Relative Atomic Mass.
State the meaning of Gram Formula Mass (GFM).
Be able to calculate the GFM of compounds.
State that a diatomic molecule is made up of two atoms.
Give examples of elements which exist as diatomic molecules.
