Answer:
Beryllium, because it is in period 2 and has four total electrons.
Explanation:
Yes becuase it says it maintains its velocity if it is moving or at rest
The reaction will come to an end if all the reactants are used up. The reaction's limiting reactant is reactant B.
Limiting Reactant: The limiting reactant is the one that is consumed first and sets a limit on the quantity of product(s) that can be obtained.
This reactant is the one that restricts the production of products throughout the reaction. The reaction will come to an end if all of the reactants are used up.
surplus reactant
This is the limiting reactant that is present in excess and reacts with it all. Oxygen in the surroundings, as an illustration.
When all of the reactant B has been utilized, the reaction ends.

6 because the number of valence electrons is always the ones-place of any two-digit group number. So an element in group 18 would have 8 valence electrons
Hope this helps!
