What are the trends patterns in Group 1?
Explaining the trend The reactivity of group 1 elements increases as you go down the group because: the atoms become larger. the outer electron becomes further from the nucleus. the force of attraction between the nucleus and the outer electron decreases.
What are the patterns in the properties of the Group 1 metals?
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 is the pattern going down Group 1?
Progressing down group 1, the atomic radius increases due to the extra shell of electrons for each element. Going down the group, the first ionisation energy decreases. Generally the melting point of the alkali metals decreases down the group.
What is the pattern of groups in the periodic table?
The periodic table is an arrangement of the elements in order of increasing atomic number. Elements that exhibit similar chemistry appear in vertical columns called groups (numbered 1–18 from left to right); the seven horizontal rows are called periods.
What do atoms of group1 elements do have in common?
The Group 1 elements have similar properties because of the electronic structure of their atoms – they all have one electron in their outer shell.
What properties does group 1 have?
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.
Why does MP and BP decrease down Group 1?
When any of the Group 1 metals is melted, the metallic bond is weakened enough for the atoms to move more freely, and is broken completely when the boiling point is reached. The decrease in melting and boiling points reflects the decrease in the strength of each metallic bond.
Which is not a part of Group 1?
Note: Even though Hydrogen will appear above Lithium on the periodic table it is not considered a part of Group 1. Group 1 elements are known as Alkali Metals. They are called s-block elements because their highest energy electrons appear in the s subshell.
What are the reactivity patterns of Group 1 elements?
Reactivity Patterns in Group 1 and Group 7 Elements 1 THE HIGHER THE NUMBER OF VALENCE SHELLS… 2 THE MORE EASILY THE ELECTRONS ARE LOST AND 3 THE LESS EASILY THE ELECTRONS ARE GAINED
What are the physical properties of Group 1?
The elements in group 1 are called the alkali metals. Group 1 is on the left-hand side of the periodic table. The alkali metals share similar physical properties. For example, they: are soft (they can be cut with a knife) have relatively low melting points. have low densities.
How are Group 1 elements similar to each other?
They have the same number of electrons in their outer shell, so they are similar in their chemical properties. Group 1 contains elements placed in a vertical column on the far left of the periodic table. The elements in group 1 are called the alkali metals. The alkali metals share similar physical properties. For example, they:
