Express the set of natural numbers less than 7 in roster form

The expression to the statement in roaster form is:

{1,2,3,4,5,6}

Step-by-step explanation:

" To express the set in roster form the elements of a set are listed within the curly brackets and are separated by commas " .

We are given a statement as:

" The set of natural numbers less than 7" is represented in roaster form as:

{1,2,3,4,5,6}

( since, the natural numbers are the positive integers (whole numbers) 1, 2, 3, etc. and we asked to find the numbers less than 7).

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.

50-60=10
