(I got 4 questions for the day.) Isotopes are elements with the same # of protons but a different # of.
A. Electrons
B. Neutrons
C. Atoms

How many Neutrons are in this isotope of oxygen?
A.8

C.10
D.12

How many neutrons are in this isotope of carbon?
A.6
B.7
C.13
D.19

How many neutrons does the isotope of phosphorus have?
A.15
B.25
C.10
D.5
​

A) Electrons

A) 16-8=8 so it'd be 8

(Relative atomic mass - atomic number = neutrons)

A) 12

Same thing as last one.

31-15=16 ( did you type the wrong options if not then huh?)

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
