Question

subscripts are small numbers after the symbol of an element. for example, the 2 in o₂ is a subscript. subscripts tell you how many atoms of that element there are. for examples there are 2 oxygen atoms in o₂. if there is no subscript after an element, it means that there is just one atom of that element. write the number of each element in the molecules below. the first one is done for you. 1. f₂ there are 2 atoms of fluorine 2. c there are __ atoms of carbon 3. h₃ there are atoms of hydrogen 4. s there are __ atoms of sulfur

Explanation:

Step1: Identify carbon's subscript

For carbon (C), there is no subscript after it. According to the rule, no subscript means 1 atom.

Step2: Identify hydrogen's subscript

For hydrogen (H), the sub - script is 3, so there are 3 atoms of hydrogen.

Step3: Identify sulfur's subscript

For sulfur (S), there is no subscript after it, so there is 1 atom of sulfur.
