Write 23,665,700 in Scientific Notation with 4 significant figures.
Aloiza [94]

<u>Answer:</u> The given number in scientific notation is 2.367\times 10^{7}

<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.

\Rightarrow 23,665,700=2.367\times 10^{7}

Hence, the given number in scientific notation is 2.367\times 10^{7}

Write the full electron configuration of the Period 2 element with the following successive IEs (in kJ/mol):
Julli [10]

Answer:

Boron (B) is the element whose IE matches with our data.

Electronic Configuration of boron: 1s^22s^22p^1

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: 1s^22s^22p^1

Boron has 5 electrons (3 in valance shell) that's why it has 5 Ionization Energies.

5. What could you do to convert from meters to centimeters? *
maria [59]

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.
