Suppose a company needs temporary passwords for trial of a new management software. each password will have two letters followed by two digits. the digits 7,8,and 9 will not used. so, there are 26 letters and 7 digits that will be used. assume that the letters and digits can repeated. how many passwords can be created using this format

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.

yes, i think so although i am not sure. this is a very strange question.

6-3=3

3*3=9

9+12=21

21/3=7

7*8=56

56 is your answer
