Question 7 (5 points) In KCI, how are the valence electrons distributed?
A)
The electrons are unequally shared between K and Cl, forming a polar
covalent bond.
B)
The electrons are shared between many K and Cl ions, creating a "sea of
electrons."
C) The electrons are transferred from K to Cl.
D) The electrons are equally shared between K and Cl, forming a covalent bond.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

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.
