Explanation:
Group 1A consist of metals and group. 2A consist of non metals . group1A elements can become stable by donating 1 electron in the same way the elements of group 7A also becomes stable by gaining one electron . So due to being so close to being a inert gas element it is compared to the nearest noble gas.
Answer:A. Increases
Explanation:
Heating or an increase in temperature increases the kinetic energy of particles thereby increasing their motion and how they relate and react with one another.
Increase in the temperature of the solvent is directly proportional to the rate of dissolution. The rate of dissolution increases due to the increase in kinetic energy. This makes the solvent particles interact faster with the solute particles thereby increasing the dissolution rate.
Your answer is c. Hoped this has helped the
Non metals
(It’s both halogens and noble gases ) the other ones which are white(not highlighted) are alkali metals, alkaline earth metals, and transition metals :3
The answer is (2) Copper. Because copper is consist of atom. If it is decomposed, the atom will be changed. While chemical change is just the break down and form of chemical bonds between atoms.
