Answer:

The correct answer would be - 1. group 2.period 3. less 4. more

Explanation:

elements that have a place with same group contains same number of valence electrons. Thus, they will in general show comparable chemiccal properties.  

At the point when we move over a period at that point number of electrons get added to a similar shell. Therefore, there will be no expansion in size of elements.  

Additionally, metals are the elements that have a place with group 1, 2 and d-block group are otherwise called metals. Metallic character of elements diminishes when we move left to directly in a periodic table.  

As most responsive metals are put on the left half of occasional table.  

Since, size of elements increases on descending the groups. Along these lines, a elements can lose its valence electrons due to the less forrce of ttaraction between valence electrons and its neucleus.

netineya [11]
This part of the enzyme is known as the active site. Enzymes are organic molecules that catalyze certain chemical reactions in the body. A catalyst is any chemical that speeds up another reaction without being used up in the reaction itself. This means that at the end of the reaction the enzyme is able to operate on other molecules in another reaction.
