What do you think is the reason for an increasing atomic radius within one group?
2 answers:
Periodic trends are patterns on the periodic table that
illustrate elements' characteristics.
Significant trends are atomic radius, metallic
reactivity, electronegativity, electron affinity, and
ionization energy.
Atomic radius and metallic reactivity trends:
They increase when they move down a group and left
across a period.
Electronegativity, electron affinity, and ionization
energy trends:
They increase when they move up a group and right
across a period.

First, let's explain the variables. F means force, m means mass, and a means acceleration. F is measured in Newotns [N], mass is measured in kilograms [kg], and acceleration in measured in meters per squared second [m/s²].
Now let's mover on the first problem.
Given
m = 1000 kg
a = 3 m/s²
According to the second law of Newton, the force is equal to the acceleration multiplied by the mass.
The answer is 3000 N.
The second problem is smiliar.
Given
m = 70 kg
F = 250 N
We use the same formula from before, and use a bit of algebra to adapat it to our needs.
The answer is 24 1/7 s/m^2.
