1

Step-by-step explanation:

Given : A bag contains 7 apples and 5 oranges.

Then , the total number of pieces of fruits =

We know that the number of n things taken x at a time is given by:-

Then, the number of ways you can get 7 apples:-

Hence, the number of ways you can get 7 apples =1

x=30

step-by-step explanation:

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.
