What follows an element's symbol in a chemical formula to indicate the number of atoms of that element in one molecule of the compound?
a. number in parentheses
b. subscripted number
c. superscripted number
d. charge sign
2. the chemical formula for an ionic compound represents one
a. molecule.
b. formula unit.
c. cation.
d. ion.

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;

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.  

diaria maybe go see a doctor about that
