<u>Answer:</u> The given number in scientific notation is 
<u>Explanation:</u>
Scientific notation is the notation where a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....
If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.
We are given:
A number having value = 23,665,700
Converting this into scientific notation, we get:
As, the decimal is shifting to left side, the power of 10 will be positive.

Hence, the given number in scientific notation is 
Answer:
Boron (B) is the element whose IE matches with our data.
Electronic Configuration of boron: 
Explanation:
Ionization Energy (IE):
It is the minimum amount of energy which is required to remove the lose electron. If the electron is closer to the nucleus then greater amount of energy is required to remove the electron.
If we look from left to right in a period, ionization energy increases due stability of valance shell.
From the data given to us:
IE₁ = 801
IE₂ = 2427
IE₃ = 3659
IE₄ = 25,022
IE₅ = 32,822
Boron (B) is the element whose IE matches with our data.
Electronic Configuration of boron: 
Boron has 5 electrons (3 in valance shell) that's why it has 5 Ionization Energies.
Answer:
Sulfur
Explanation:
Sulfur is a chemical element that is represented with the chemical symbol "S" and the atomic number 16 on the periodic table.
C.
centi- is essentially 10^2 of one meter.
If you had 100m, multiplying 100 by 10^2 (or 100) would give you 10000 cm.
