Answer:
Elements that are found in the same horizontal row (belong to the same period) in the periodic table, e.g. Fluorine and Neon both have the same energy level of 2.
<em>Note: The question does not specify any two elements.</em>
Explanation:
The modern periodic table is organized into eight vertical columns known as groups and seven horizontal rows known as periods. The atomic number ( number of protons in the nucleus) of elements increases when moving across the periodic table from left to right. The horizontal rows or periods represents an energy levels or the number of electron shells in an element. Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Elements belonging to the same period have the same number of energy level or shells. For example, the elements belonging to Period 2 include lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine and neon. These all have the same number of energy level of 2.
If the producers were removed then there would be no beginning to the food chain and the complete ecosystem would die off. If the detrivores and decomposers were removed there would be no organic nutrients and all the dead plants would ruin the animals habitat.The ecosystem will be fill by plants and animal wastes as <span>there will be no decomposition of waste material.</span>
Answer:
d is zero (0)
Explanation:
ψ(x)=ce^κx+de^−κx
Let say x = - 1000
We have something like
ce^κ* -1000 = approximately zero
Where we assume k to be 1
C becomes zero as it tend to negative infinity
But
If k is 1
de^−1* 1000 =d * 2 * 10^434
To have a zero function d = 0
So 0 * 2 * 10^434 = 0
