What are the chemical properties for Group 1?
The alkali metals are a group of chemical elements in the periodic table with the following physical and chemical properties:
- shiny.
- soft.
- silvery.
- highly reactive at standard temperature and pressure.
- readily lose their outermost electron to form cations with a charge of +1.
What do group 1 elements all have in common?
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 does Group 1 contain?
Alkali metals are the chemical elements found in Group 1 of the periodic table. The alkali metals include: lithium, sodium, potassium, rubidium, cesium, and francium.
Why do all elements in Group 1 have similar properties?
Atoms of group 1 elements all have one electron in their outer shell. This means that the alkali metals all have similar chemical properties . When a group 1 element takes part in a reaction, its atoms each lose one electron. The ions have a stable arrangement of electrons, with a complete outer shell.
Can Group 1 metals conduct electricity?
The metals in Group 1, such as lithium, sodium and potassium, are all soft. The properties of metals can be used to explain typical uses of metals. For example, copper is used for wiring because it is ductile and a good conductor of electricity. Its ability to conduct heat is not relevant for this use.
Why is Group 1 most reactive?
The reactivity of Group 1 elements increases as you go down the group because: the outer electron gets further from the nucleus as you go down the group. the attraction between the nucleus and outer electron gets weaker as you go down the group – so the electron is more easily lost.
Why group 1 elements are soft and have low melting and boiling points?
Alkali Metals features the large atomic radii between neighbouring atoms of Group 1. Hence, the molecules show weaker attractive forces and are soft and have low melting points.
