Select the correct answer below:

A. O2-

B. F-

C. N3-

D. S2-

B. F⁻

Explanation:

Which anion would bond with K⁺ in a 1:1 ratio to form a neutral ionic compound?

Select the correct answer below:

A. O²⁻. NO. K⁺ and O²⁻ form K₂O in a 2:1 molar ratio.

B. F⁻. YES. K⁺ and F⁻ form KF in a 1:1 molar ratio.

C. N³⁻ . NO. K⁺ and N³⁻ form K₃N in a 3:1 molar ratio.

D. S²⁻. NO. K⁺ and S²⁻ form K₂S in a 2:1 molar ratio.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
