Identify the ordered pair that represents the vector from A(-99) to (7,3) and the magnitude of AB.
a. 4-7, 18), 288 N 15.088
c. (17. - 1) 299 x 19.088
b. (16. - 6.). 1292 N 17.088
d. (17. - 7)1294 18.088

b. bruv

Step-by-step explanation:

got it on edge

answer: i think it is (1,-2)

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.
