Verified step by step guidance1
Understand that chemical symbols are one- or two-letter abbreviations derived from the element's English or Latin name, used to uniquely identify each element on the periodic table.
Recall that the chemical symbol for zinc is derived from its English name 'Zinc', and typically the first letter is capitalized, followed by a lowercase letter if there is a second letter.
Evaluate the options given: 'Z' is the symbol for zinc's atomic number but is not the correct symbol; 'Ze' and 'Zc' do not correspond to any element on the periodic table.
Recognize that the correct chemical symbol for zinc is 'Zn', where 'Z' is capitalized and 'n' is lowercase, following the standard convention for element symbols.
Confirm that 'Zn' is the accepted and official chemical symbol for zinc as listed in the periodic table.
