An element that has 10 protons, 9 electrons, and 11 neutrons. What is the net/ionic charge of this atom? A) -2

B) -1

C) +1

D) +2

(C) +1

Explanation:

Neutrons have no charge, so we can ignore them in this problem. Protons have a 1+ charge, and electrons have a 1- charge. So, the total charge is 10(+1) + 9(-1) = +1.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)

i believe the answer is a hope it and is correct
