There are 17 nutrients that essential for the growth of the plants. These nutrients are classified into two categories on the basis of requirement micronutrients (required in less amount) and macronutrient (required in large amount). The three primary nutrients needed for plant growth are nitrogen, phosphorous and potassium.
The electrons that are in the outermost electron shell, also known as the valence shell, have more energy then those in the inner electron shells, I hope this helps<3
In physics, the law of conservation of energy states that the total energy of an iolated system remains constant, it is said to be conserved over time. energy can neither be destroyed rather it transforms from one form to another.
Explanation:
Since, Number of shells in an atom = number of period
Therefore, atoms of element will have 4 shells.
For example:
K (Potassium) is an element of 4th period whose atomic number is 19.
19 = 2, 8, 8, 1
After 3 days = 500g becomes 250g
After 6 days = 250g becomes 125g
After 9 days = 125g becomes 62.5g
After 12 days = 62.5g becomes 31.25g
After 15 days = 31.25g becomes 15.625g
After 18 days = 15.625g becomes 7.8125g
After 18days, you would have about 7.813g left.
