Where are type two metals found on the periodic table?
Metals are found in group-1 and 2. Group-1 are called alkalis and group-2 are called alkaline earth metals.
Why are group 1 metals largely ionic?
The group 1 metals are softer because of weaker electrostatic forces. This is thought to be because of the lower amount of valence electrons (electrons in outer shell) but it isn't certain.
What are the elements in group 1 of the periodic table are what metal?
The group one metals or alkalis metals are found in group 1 of the periodic table are very reactive metals. These metals have only one electron in their outer shell. Therefore, they are ready to lose that one electron in ionic bonding with other elements. As with all metals, the alkali metals are shiny and easy to cut and are good conductors of heat and electricity. The alkali metals are softer than most other metals. Caesium and francium are the most reactive elements in this group.
3 How does reactivity change as you go down Group 1 Does the same pattern hold for group 2?
As you go down Group 1 (alkali metals), reactivity increases due to the lower ionization energy, making it easier for these metals to lose their outermost electron. In contrast, Group 2 (alkaline earth metals) also shows an increase in reactivity down the group, but the trend is less pronounced compared to Group 1. This is because while ionization energy decreases, the presence of two outer electrons means that the reactivity is not solely dependent on losing one electron. Overall, both groups exhibit increasing reactivity down the group, but the rate of change is stronger in Group 1.
As you move down a group elements have how many electrons shells than those above them?
going down a group, each element gains 1 shell (energy levels)
What does group one of the periodoic table consist of?
Group 1, alkalis metals: Li, Na, K, Rb, Cs, Fr.
Where are type two metals found on the periodic table?
Metals are found in group-1 and 2. Group-1 are called alkalis and group-2 are called alkaline earth metals.
Is Na an alkaline metal?
Yes na/Sodium is an alkali metal. All metals in group 1 are alkalis.
List four properties of alkalis?
alkalis are corrosive, normally water soluble and are very soapy.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
Why are lithium potassiumand cesium classified as alkalis metals?
They are all group 1 elements and react with water to from the corresponding hydroxides which act as alkali (base). Hence the name.
Why are group 1 metals largely ionic?
The group 1 metals are softer because of weaker electrostatic forces. This is thought to be because of the lower amount of valence electrons (electrons in outer shell) but it isn't certain.
Elements in group 1?
The elements of 1st group are known as Alkalis and They are said to be in Lithium Family. The element are Lithium (Li) , Sodium (Na) , Potassium (K) , Rubedium (Rb) , Cesium (Cs) , Francium (Fr)
Name 2types of alkalis used in the home?
1) oven cleaner 1) human sliva
What elements are in alkalis?
There may be many. Li, Na, K, Rb, Cs, Fr, Be, Mg, Ca, Sr, Ba, Ra all form alkalis. They do so with water by forming the hydroxide. So to the list we would have to add the elements O and H. The carbonates of the above are also alkali so the element C could be added.
Are alkalis and acids dangerous?
Alkalis and acids can be dangerous if handled improperly. They can cause burns, irritation, and other harmful effects if they come into contact with skin, eyes, or other tissues. It is important to use appropriate precautions when working with alkalis and acids to prevent accidents and injuries.
Is a No. 1 pencil harder or softer than a No. 2 pencil?
It's softer. #1 softest, #2 slightly harder, #3 harder than #2, etc.Softer.a #1 pencil is softer than a#2 pencil
