O is the standard chemical symbol for Oxygen. The symbol is derived from the element's English name and is widely recognized on the periodic table.

H is the chemical symbol for Hydrogen. Helium is denoted by He, so it is important to distinguish between the two.

C is the correct chemical symbol for Carbon, one of the most fundamental elements in organic chemistry. Its simplicity makes it one of the easiest symbols to remember.

Na is the symbol for Sodium, which originates from the Latin name 'Natrium'. Recognizing Latin roots in element names is key to understanding chemical symbols.

Fe stands for Iron on the periodic table, derived from its Latin name 'Ferrum'. This connection is a classic example of non-intuitive chemical symbols.

Au is the chemical symbol for Gold, which is derived from the Latin word 'Aurum.' Recognizing such Latin origins makes it easier to remember the symbol.

K is the chemical symbol for Potassium, originating from the Latin word 'Kalium.' This is a common example of a symbol that does not match the English name.

Sodium is represented by the symbol Na, from its Latin name 'Natrium.' This discrepancy between its English name and symbol is a classic example in chemistry.

N is the correct chemical symbol for Nitrogen. Its symbol is directly derived from its name, making it straightforward for students to remember.

Neon is the noble gas represented by the symbol Ne. Noble gases are known for their inert properties due to having complete electron shells.

Pb is the chemical symbol for Lead, which comes from its Latin name 'Plumbum.' Recognizing these derivations is essential for a deeper understanding of the periodic table.

Ag is the symbol for Silver, derived from the Latin word 'Argentum.' This is a classic example of how chemical symbols often have historical roots.

Ca is the chemical symbol for Calcium, taken from the first two letters of its name. This simple abbreviation is a standard convention in chemistry.

Si stands for Silicon, an essential element used in computer chips due to its semiconductor properties. Its application in technology underscores its importance in modern chemistry.

Mg is the correct chemical symbol for Magnesium, derived directly from its name. This makes it one of the more straightforward examples on the periodic table.

Na is the chemical symbol for Sodium, with its origin traced back to the Latin name 'Natrium.' Understanding this historical naming convention is important in mastering chemical symbols.

Tungsten is represented by the symbol 'W' because its alternative name, Wolfram, influenced its abbreviation. This non-intuitive symbol is a common point of confusion and an important detail to remember.

Hg is the chemical symbol for Mercury, derived from the Latin 'hydrargyrum', meaning 'liquid silver.' This non-intuitive symbol is vital to recognize when studying the periodic table.

Lead is correctly paired with the symbol Pb, which comes from its Latin name 'Plumbum.' The other pairs do not accurately reflect the standard abbreviations found on the periodic table.

Tin is denoted by the symbol 'Sn,' which is derived from its Latin name 'Stannum.' This difference between its English name and symbol is a classic example of the historical influences in chemical nomenclature.
