On monday 336 fourth graders went on a field trip to a local park. the teachers divided them into 8 groups. use a basic fact. estimate the number of students in each group.

42 students

Step-by-step explanation:

If 336 fourth graders went on a field trip to a local park and they are divided into 8groups, the estimate number of students in each group will be gotten using the formula;

Number of student in each group= total number of students/total number of groups

Number of students in each group = 336/8 = 42

This means that there are 42students in each group.

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.
