What do forces have to do with atomic radius of alkali metals?
Forces have an indirect impact on the atomic radius of alkali metals. As you move down a group of alkali metals in the periodic table, the atomic radius typically increases due to increased electron shells. The forces between the electrons and nucleus (electrostatic forces) contribute to the overall size of the atom in terms of atomic radius.
Why do melting points get lower as you go down group 1?
There is no "generally". For alkali metals (group 1) and alkali earths (group 2) they decrease. For groups 4 to 10 they rise, for group 11 it goes down from copper to silver and then up to gold.
What is a pattern of alkali metals?
if you search the periodic table and find you can see the numeric value numbers of 1 to 8 then shortly you will see the radius will increase vigourusly showing the bottom and top number at any one time then that is how to get the radius separated from the core nucleus
Which alkali earth metal has the smallest atomic radius?
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four
What alkali metal has an atomic radius of 238 pm?
The alkali metal with an atomic radius of 238 pm is potassium (K). Its large atomic radius is due to the added electron shells compared to other alkali metals in the same period.
Why melting point decrease down the group for Alkali metals but increase for Halogens?
The melting point decreases down the group for alkali metals because the metallic bonding weakens as the atomic size increases, resulting in weaker intermolecular forces. For halogens, the melting point increases down the group due to stronger van der Waals forces between larger molecules with increased electron cloud size, resulting in higher melting points.
How do you decrease the size of a circle?
Decrease The Length of The Radius
Is chlorine's atomic radius bigger or is bromine's?
The atomic radius of bromine is bigger.
What is the biggest element in the alkali family?
Francium has the biggest atomic weight and the biggest atomic radius between the alkali metals.
Why do alkali's get softer down the group 1?
Alkali metals get softer down Group 1 due to an increase in atomic size and weaker metallic bonding. As you move down the group, the atomic radius increases, leading to a decrease in the strength of metallic bonding and making the metals softer.
What is the relationship between melting points and boiling points of alkali metals?
From BCIT.ca: The alkali metals show a decrease in melting points and boiling points due to the weaker metallic bonds between atoms as their size increase down the group.From AUS-e-TUTE: melting point decreases down the Group as the elements become less metallic in natureFrom okstate.edu: As one goes down the Periodic Table, the metallic radius of alkali metals increases. The increase in radius results in much decreased attractive forces between atoms within the liquid metals, resulting in a decrease in heat of vaporization and boiling points [and melting points] because less heat is needed to separate atoms from the liquid [or solid] state within the larger alkali metals.

How many times bigger than the earths radius is the suns radius?
the sun's radius is and half a million bigger than the radius of the sun.
