When metals react with water for class 8?
Very reactive metals - from group 1 and 2 of the periodic table - can react with water.
What group of elements react by losing one electron?
The alkali metals in group 1 react by losing one electron.
Why is group 1 metals called alkali metals?
Group 1 metals are called alkali metals because they form alkaline solutions (pH greater than 7) when they react with water. They are highly reactive and easily lose their outermost electron to form positive ions, which makes them behave in a similar manner to the alkaline earth metals.
Do metals in group 1 react more with water than in acid?
yes
How do group 7 halogens react with metals?
Group 1 metals react with halogens through electron configuration. Group 1 (Alkali) metals have one electron in their outer shell.
Which metals react slowly with cold water but vigorously with steam?
All metals, if they do react with water at all, react faster in steam than in water. However, the metals that react SLOWLY with cold water are the metals from Group-IIA(Magnesium, Calcium, etc).
When metals react with water for class 8?
Very reactive metals - from group 1 and 2 of the periodic table - can react with water.
What do metals react with that is found in the air?
group one and two metals react with oxygen in the air as well as moisture to from metal oxides
What group of elements react by losing one electron?
The alkali metals in group 1 react by losing one electron.
What substances might react as a group to metals?
For example acids.
Why are group 1 metals knowns as alkali metals?
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
Why is group 1 metals called alkali metals?
Group 1 metals are called alkali metals because they form alkaline solutions (pH greater than 7) when they react with water. They are highly reactive and easily lose their outermost electron to form positive ions, which makes them behave in a similar manner to the alkaline earth metals.
Do metals in group 1 react more with water than in acid?
yes
Which group on the periodic table contain metals that react vigorously to water?
Alkali Earth metals are the most reactive metals on the periodic table.
How do you test the reactivity of metals?
The reactivity of metals can be tested by observing their reaction with water, acids, or oxygen. More reactive metals will react vigorously and produce products such as hydrogen gas or metal oxides, while less reactive metals may not react at all or only react slowly. The reactivity series of metals can be used as a reference to determine their relative reactivity.
Pattern of reactions of metals with oxygen?
The pattern of reactions of metals with oxygen is based on their position in the reactivity series. Highly reactive metals like potassium, sodium, and calcium react vigorously with oxygen to form metal oxides. Less reactive metals like iron and copper react slowly with oxygen, forming metal oxides or hydroxides. Noble metals like gold and platinum do not react with oxygen at all under normal conditions.
What metals that lose one electron when they react with water to form alkaline solutions?
The metals that lose one electron when they react with water to form alkaline solutions are group 1 and group 2 metals such as lithium, sodium, potassium, calcium, and magnesium. These metals are highly reactive and readily donate their outermost electron to form cations that react with water to produce alkaline solutions.
