39
The pattern involving orbitals and periods
Each period you go down, the orbital increases by one
40
The pattern to do with valence electrons and groups
The valence electrons increase by one each group, excluding groups 3-12
41
The main families on the periodic table and where they are located (5)
Alkali metals (group 1), alkaline earth metals (group 2), transition metals (groups 3-12), rare earth metals (2 rows at the bottom), halogens (group 17), noble gases
42
As you move down a column, elements become more... because....
Reactive, this happens because they have more energy because they have more energy
43
Atomic radius ______ as you go down a group, because....
Increases, this is because there are more protons and neutrons so the nucleus is bigger
44
What is an example of two groups that are extremely reactive w each other and what is the reasoning
Alkali metals and halogens: this is because they are both aiming for a full valence shell and to achieve that alkalis have to lose one and halogens have to gains one
45
Physical properties of metals
Shiny, solid, high density, strong, malleable, good conduction of heat, good conductor of electricity,
46
Physical properties of non-metals
Dull, about half are solids, half are gases and one (bromine) is a liquid, low density, weak, brittle, poor conduction of heat and electricity (insulators)
