What are the properties of the groups on the periodic table?
Characteristics of groups and periods in a periodic table
- Atomic Size: From top to bottom in a group, the size of atom increases as a new shell to the atom.
- Valence Electrons(V.E) : Number of valence electrons in a group are same.
- Valency: All elements in a group generally have the same valency.
What are the groups families and their properties?
9 Element Families Alkali Metals: Group 1 (IA) – 1 valence electron. Alkaline Earth Metals: Group 2 (IIA) – 2 valence electrons. Transition Metals: Groups 3-12 – d and f block metals have 2 valence electrons. Boron Group or Earth Metals: Group 13 (IIIA) – 3 valence electrons.
What are the 5 groups of the periodic table?
Group 5 (by IUPAC style) is a group of elements in the periodic table….Chemistry.
| Z | Element | No. of electrons/shell |
|---|---|---|
| 23 | vanadium | 2, 8, 11, 2 |
| 41 | niobium | 2, 8, 18, 12, 1 |
| 73 | tantalum | 2, 8, 18, 32, 11, 2 |
| 105 | dubnium | 2, 8, 18, 32, 32, 11, 2 |

What are the properties of group 2 elements?
These physical properties of group 2 elements are:
- low density (mass over volume)
- low melting points (except beryllium)
- low boiling points (except beryllium)
- soft and strong in their metal states.
- ductile.
- malleable.
- shiny and silvery as metals.
- dull appearance.

What are the properties of Group 5?
Lesson Summary
- Group 5A elements contain 5 valence electrons.
- They have several different oxidation states.
- They usually form covalent bonds but can also form ionic bonds.
- They include non-metals, metalloids and metals.
- All are solids at room temperature except nitrogen.
What are the physical properties of group 1 elements?
Group one elements share common characteristics. They are all soft, silver metals. Due to their low ionization energy, these metals have low melting points and are highly reactive. The reactivity of this family increases as you move down the table.
What are the physical properties of Group 7 elements?
The halogens have low melting points and low boiling points. This is a typical property of non-metals. Fluorine has the lowest melting and boiling points. The melting and boiling points then increase as you go down the group.
What are the properties of Group 17 in the periodic table?
The halogens are the elements that form group 17 of the periodic table. They are reactive nonmetals and include fluorine, chlorine, bromine, and iodine. Halogens are highly reactive non-metals. These elements greatly resemble in property with each other.
What are the properties of Group 2 elements?
What are the properties of Group 18?
The members of the group have eight electrons in their outermost orbit (except helium which has two electrons). Thus, they have a stable configuration. Group 18 elements are gases and chemically unreactive, which means they don’t form many compounds. Thus, the elements are known as inert gases.
What are the properties of group 17 elements?
Physical properties of Group 17 elements
| Element | Fluorine | Chlorine |
|---|---|---|
| Atomic radius (nm) | 0.071 | 0.099 |
| Density (g cm-1) | 0.0017 | 0.0032 |
| Melting point (°C) | -220 | -101 |
| Boiling point (°C) | -188 | -35 |
What are the physical properties of Group 18 elements?
Atomic radius (atomic size) The atomic radii (atomic sizes) of noble gases increase when going down Group 18 from helium to radon.
