fill in each blank

Question

Chemical formulas can have three components. The ________________ which are represented by a single uppercase letter, or represented by an uppercase letter followed by a lowercase letter. This tells you the types of elements in the compound. The ________________ which are numbers that are found on the lower ________________- hand side
of each element symbol. This tells you the number of ________________ of this element in the
molecule. If an element symbol has no subscript next to it, then this indicates that there is only
________________ atom of this element in the molecule. The ________________ which surround some groups of atoms indicate that the numbers of all of the atoms inside the bracket need to be ________________ by the ________________ on the outside of the bracket found on the lower ________________ - hand side of that bracket.

Answer 1

Chemical formulas can have three components. The first component is the element symbols which are represented by a single uppercase letter, or represented by an uppercase letter followed by a lowercase letter. This tells you the types of elements in the compound. The second component is the subscripts which are numbers that are found on the lower right-hand side of each element symbol. This tells you the number of atoms of this element in the molecule. If an element symbol has no subscript next to it, then this indicates that there is only one atom of this element in the molecule. The third component is the coefficients which surround some groups of atoms and indicate that the numbers of all of the atoms inside the bracket need to be multiplied by the coefficient on the outside of the bracket found on the lower left-hand side of that bracket.
