Afarm supply store carries 50-lb bags of both grain pellets and
grain mash for pig feed. it can store 600 bags of pig feed. at least
twice as many of its customers prefer the mash to the pellets. the
store buys the pellets for $3.75 per bag and sells them for $6.00. it
buys the mash for $2.50 per bag and sells it for $4.00. if the store
orders no more than $1400 worth of pig feed, how many bags of
mash should the store order to make the most profit?

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.
