Answer:
Point out that when water freezes, the water molecules have slowed down enough that their attractions arrange them into fixed positions. Water molecules freeze in a hexagonal pattern and the molecules are further apart than they were in liquid water.
It is an inverse relationship as the period increases the orbital radius decreases
Answer:
Explanation:
1. Increasing the concentrations of reactants in a chemical reaction would affect a reaction positively by increasing the number of collisions within a particular period which in turn increases the rate of reaction.
2. The molecules gains energy,which enable them to move faster and collide with the right energy for a reaction to take place.
3. The average kinetic motion of molecules in a solution can be measured by measuring the temperature. Temperature is a measure of the average kinetic energy of molecules in a solution.
Your answer is A my friend as the atomic number of an atom is determined by the number of protons
