What is the difference between alkali metal and group 2 metals?
Alkali metals have one valence electron, group 2 metals have 2.
What metal reacts with hot water?
The metals that react violently with cold water are group 1 and group 2 metals. Reactivity increases going down the group and to the left of a period.
Which 2 groups of metals are the most reactive?
1. alkaline metals 2. alkaline earths metals
Elements in group 2 are called?
Group 2 elements in the periodic table are the alkaline earth metals.
What are the oxidation numbers for the metal groups 1A 2A 3A?
Group 1 or alkali metals (+1 oxidation number). Group 2 or alkaline earth metals (+2 oxidation number).
Are Alkali metal hydroxides and alkaline earth metal hydroxides strong metals?
Alkali metals are metals in Group I (far left column) such as Lithium, Sodium, Potassium, etc. They have a valence of -1.Alkali Earth Metals are in Group II (second column from the left) such as Berylium, Magnesium, Calcium, etc. and have a valence of -2.One Hydroxide (OH-) ion will form an ionic bond with group 1 elements {Like NaOH }, and two Hydroxide ions will form an ionic bond with group 2 elements {like Ca(OH)2 }
Are all metal hydroxides strong soluble bases?
No. Not ALL metal hydroxides are strong bases, and not all strong bases are soluble.Only group 2 hydroxides (LiOH, NaOH, KOH, etc) and three group 2 metal hydroxides (CaOH, SrOH, and BaOH) are strong bases.Solubility is determined by how much the substance deionizes in a solution at a given temperature. A soluble substance is considered to be soluble if makes 0.1 M, and insoluble if it's less than 0.0001 M.For example, BaOH is a strong base, and is considered insoluble because less than 1% of it dissolves in water. But the bit that does is a very strong electrolyte.
How many moles of OH ions are produced from the hydroxides of group ii metals for every mole of the base that dissociates?
That would be 2 moles of OH- (hydroxide) ions because there are 2 of them associated with each 1 of the group II metal.
When metals react with water for class 8?
Very reactive metals - from group 1 and 2 of the periodic table - can react with water.
Are transition metals on the periodic table reactive?
yes, they are less reactive than group 1 and 2. These metals hardly react with air or water at all whereas Group 1 and 2 metals tarnish quickly and react with water
What happens when metal reacts with water?
Most metals react VERY slowly, but some react vigorously .Metals will produce either the hydroxide or oxide....Did that help...?Hope it did...BYE :)

WHERE ON THE PERIODIC TABLE IS THE METALS?
Metals are on the left side in periodic table. They are mainly present in group-1,2,13. Group-1 is alkali metals and group-2 is alkaline earth metals.Group 1 contains alkaline metals. Group 2 contains alkaline earth metals. And d block also contains metals.
Which 2 groups of metals are the most reactive?
1. alkaline metals 2. alkaline earths metals
What is the group of alkaline earth metals?
Group 2 contains the alkaline earth metals
With metals having a fixed oxidation number?
Group 1 and group 2 metals with +1 and +2 respectively
