Lincoln Elementary School was having a bake sale. 18 different people made two dozen (24) items for the sale. How many items did they have for the sale?

They had 24 items for the sale.

Step-by-step explanation:

Given: In baking sale,

18 different people made 2 dozen items for the sale.

We know that,

1 dozen = 12 items

2 dozens = 2 x 12 items

i.e. 2 dozens = 24 items

Therefore, they will have 24 items for sales if they made 2 dozens items.

Hence, they had 24 items for the sale.

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.
