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.

root word, prefixes, and suffixes

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
