The table shows the total number of electrons in atom a and atom b. atom number of electrons a 11 b 17 which statement is correct? a will give up electrons to form bonds. b will give up electrons to form bonds. both a and b will be chemically unreactive. both a and b will gain electrons to become stable.

A will give up electrons to form bonds.

Step-by-step explanation:

The shell configuration of atoms is 2, 8, 8, 18, …

Thus, an atom has a filled shell when it has two electrons or ten (2 + 8) electrons or 18 (2 + 8 + 8) electrons.  

A has 11 electrons, one more than necessary for a filled shell. It will give up that electron to reach a filled shell.

Option B is wrong. B has 17 electrons, one less than is needed for a complete shell. It will gain electrons to reach a filled shell.

Option C is wrong. Both A and B will be chemically reactive, because each is only one electron short of a complete shell.

Option D is wrong. Both A and B can’t gain electrons. You can’t create electrons out of nothing. If one atom gains electrons, another atom must lose them.

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.

it is a solid
