Each atom/element has an electron configuration
The electron configuration shows the energy level of the electron
Each electron configuration has 4 quantum numbers, namely n, l, ml, and ms
- n = the principal
- l = the angular momentum / azimuthal
- ml = the magnetic
- ms = the electron-spin
We make an example of the element Mg which is in group 2 with the atomic number 12
Electron configuration of Mg: [Ne] 3s² or 1s² 2s² 2p⁶ 3s²
if Mg removes 2 electrons then Mg will form a positive ion (cation) Mg²⁺
This cation is included in the monatomic ion because it is formed from one element (in contrast to the polyatomic ion, which is formed from two or more elements such as SO₄²⁻, ClO₃⁻)
Electron configuration of Mg²⁺ : 1s² 2s² 2p⁶
So atoms can be positively or negatively charged depending on removing or attracting electrons
If a large leak of refrigerant occurs such as from a filled cylinder in an enclosed area, the correct action that should be taken when no self-contained breathing apparatus is available would be to vacate the spill area and ventilate it. Leaving the area of the spill should be done as fast as possible to avoid suffocation of the refrigerant or other health effects like burns and irritations. Also, diluting it with air or ventilating it would make it less harmful to the people affected by the spill as it would be less harmful than being in its concentrated form.

The environment modifies.
Explanation:
A modification of the environment can lead to population changes overtime. The environment is very important for population dynamics.
It is predominantly made up of the factors that affects organisms and where they live.
If the resources in an environment gets depleted, organisms will be force to migrate from that place to another in search of more nutrient areas.
This and many other factor like climate, stability, etc causes changes to the population through time.
