Alberto has a mass of 52.2kg and then gains 2kg . frank has a mass of 48.8 and then loses 3kg . after their weight change what is albee and frank's mass

After their weight change Alberto's mass is 54.2 kg and Frank's mass is 45.8 kg

Step-by-step explanation:

step 1

Find Alberto's mass after the change

Adds the kilograms he gains to its original mass

52.2+2=54.2 kg

step 2

Find Frank's mass after the change

Subtract the kilograms he losses from its original mass

48.8-3=45.8 kg

therefore

After their weight change Alberto's mass is 54.2 kg and Frank's mass is 45.8 kg

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.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
