(a)
Interpretation:
To write the chemical name of element with the symbol S.
Concept introduction:
Every element in the nature has given its own symbol, which is a shorthand method for representing the element. It is an easy way to represent the
(b)
Interpretation:
To write the chemical name of element with the symbol Sc.
Concept introduction:
Every element in the nature has given its own symbol, which is a shorthand method for representing the element. It is an easy way to represent the element by symbol instead of writing out the name of an element. The symbol of the element can be represented by one or two letters. For two letter symbols, only first letter is capitalized.
(c)
Interpretation:
To write the chemical name of element with the symbol Se.
Concept introduction:
Every element in the nature has given its own symbol, which is a shorthand method for representing the element. It is an easy way to represent the element by symbol instead of writing out the name of an element. The symbol of the element can be represented by one or two letters. For two letter symbols, only first letter is capitalized.
