Which statement is true?
A
7.9 <6.964
B
7.9 > 6.964
с
7.9 = 6.964

 B)  7.9 > 6.964

We can think of it like 7 > 6, though there's the added extra decimal bit at the end of each value. The order would be kept the same.

Writing 7.9 > 6.964 means that 7.9 is larger than 6.964

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.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
