What is the answer to this question? ? : (

58

Step-by-step explanation:

We can solve this using PEMDAS

It stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

6² ÷ 2(3) + 4

Parentheses:

There are parentheses in this question, but there is no math that needs to be done inside the parentheses.  2(3) is just multiplication.

Exponents:

We can solve the exponents:

6² ÷ 2(3) + 4

36 ÷ 2(3) + 4

Multiplication/Division:

Multiplication and division are at the same priority, so you should complete them from left to right.

36 ÷ 2(3) + 4

18(3) + 4

54 + 4

Addition/Subtraction:

We can add the last two terms.

54 + 4

step-by-step explanation:

pleaze mark brainliest!

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
