Verified step by step guidance1
Understand the components of the compound name: 'lithium chlorate' consists of lithium (Li) and the chlorate ion.
Recall that lithium is an alkali metal with a charge of +1, so its ion is Li\(\u\)207a.
Identify the chlorate ion, which is a polyatomic ion with the formula ClO\(\u\)2083\(\u\)207b and a charge of -1.
Since lithium has a +1 charge and chlorate has a -1 charge, they combine in a 1:1 ratio to form a neutral compound.
Write the chemical formula by combining Li\(\u\)207a and ClO\(\u\)2083\(\u\)207b without any additional subscripts, resulting in LiClO\(\u\)2083.
