Start Quiz
1.
Which Period 3 element has the highest melting point?
Al
Si
S
Mg
2.
Why does first IE generally increase across a period?
Shielding increases
Atomic radius increases
Nuclear charge increases with similar shielding
More shells are added
3.
Which pair shows a decrease in first IE?
Mg → Al
Na → Mg
Si → P
Cl → Ar
4.
The dip at sulfur is caused by:
a new shell
a 3d electron
a larger nuclear charge
repulsion between paired 3p electrons
5.
Why is the melting point of Al higher than Na?
Al is covalent
Al3+ is smaller with more delocalised electrons
Na has hydrogen bonds
Al has London forces only
6.
Which has the lowest melting point?
P4
S8
Cl2
Ar
7.
Which statement best describes Sub-shell repulsion?
A horizontal row of the periodic table; elements in it have the same number of occupied electron shells.
A three-dimensional network of atoms joined by strong covalent bonds, e.g. silicon.
A vertical column of elements with the same outer-shell electron configuration.
Extra repulsion between two electrons paired in the same orbital, which makes one easier to remove.
8.
Which statement best describes Group?
Extra repulsion between two electrons paired in the same orbital, which makes one easier to remove.
A horizontal row of the periodic table; elements in it have the same number of occupied electron shells.
Electrostatic attraction between a lattice of positive metal ions and delocalised electrons.
A vertical column of elements with the same outer-shell electron configuration.
9.
Which statement best describes Atomic radius?
A vertical column of elements with the same outer-shell electron configuration.
Half the distance between the nuclei of two bonded atoms of the same element.
Small molecules held together by weak intermolecular forces, e.g. P4, S8, Cl2.
The total positive charge of the nucleus, equal to the number of protons.
10.
Which statement best describes Period?
Half the distance between the nuclei of two bonded atoms of the same element.
The repeating pattern of physical and chemical properties across each period of the periodic table.
A horizontal row of the periodic table; elements in it have the same number of occupied electron shells.
A three-dimensional network of atoms joined by strong covalent bonds, e.g. silicon.
