An atomic radius decrease across Period 3 because the number of shells not increases but the number of electron increases and the atomic size decreases as the effective nuclear charge increases.
When we move in the period 3 from left to the right the atomic radius decreases because of the reason that the the number of shells don not change they will remain the same across the period but the number of the electron will increases . the effective nuclear charge will also increases. the nucleus will attract the electrons more strongly that the reason the atomic radius decreases.
Thus, number of electron increases and the number of shells will remain same , the atomic size decreases as the effective nuclear charge increases.

Particles in a liquid move freely and liquids have a definite volume and indefinite shape since it occupies the shape of the container in which the liquid is in.
<span>The mass number of an ion is calculated by adding the neutrons and electrons together. In this case 159+107=266. However, since this ion has a +1 charge, you must add 1 to the electrons. This would give a total mass of 267.</span>
Answer:
The answer would be 1.5 kJ.
Explanation:
When you use the equation q = m x c x ∆T you will be able to find the energy gained or lost. The data for the water in this case is just there to distract you so ignore it. :D
Answer:
The human musculoskeletal system (also known as the locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body.
Explanation:
