The First 20 Elements Of The Periodic Table

The chemical symbol for the element with atomic number 1 is 'H' which stands for HYDROGEN.

The correct answer is Helium, a chemical element with atomic number 2 and symbol He on the periodic table.

The correct chemical symbol for Lithium is Li, not L, Lt, or Lu.

The correct answer is B because 'B' is the chemical symbol for Boron on the periodic table.

The correct answer is Carbon. Carbon is a chemical element with symbol C and atomic number 6. It is a nonmetallic element commonly found in nature in various forms.

The correct chemical symbol for Nitrogen is N, representing its atomic number 7 on the periodic table.

The correct answer is Oxygen, which is a chemical element with the symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table, a highly reactive nonmetal, and an oxidizing agent that readily forms oxides with most elements.

The correct chemical symbol for neon is NEON, not Na, Ni, or Ne. Neon is a noble gas with the atomic number 10.

The correct chemical symbol for Sodium is Na, derived from its Latin name 'natrium'. Sn represents Tin, Ni represents Nickel, and Au represents Gold.

The chemical symbol for magnesium is 'Mg', not 'Mn', 'Mc', or 'Mo'.

The correct chemical symbol for Aluminium is AL, while AU is the symbol for Gold (Aurum), AG is the symbol for Silver (Argentum), and AM does not represent any known chemical element.

The correct answer is SILICON, which is a chemical element with symbol Si and atomic number 14. It is a hard and brittle crystalline solid with a blue-grey metallic lustre. Silver, Sulfur, and Sodium are all different chemical elements with their own unique properties and symbols.

The correct answer is Phosphorus because its chemical symbol is 'P', while Potassium, Platinum, and Palladium have chemical symbols 'K', 'Pt', and 'Pd' respectively.

The correct chemical symbol for sulfur is S, not to be confused with other elements like Sodium (Na), Silicon (Si), and Silver (Ag).

The correct chemical symbol for chlorine is Cl, which is derived from its Latin name 'chlorum'. The incorrect options are: C (for carbon), Cl2 (which would be a molecule of chlorine gas), and CN (for cyanide).

The correct chemical symbol for Argon is Ar, not Ag (Silver), Au (Gold), or As (Arsenic).

The correct answer is Potassium, which is represented by the chemical symbol 'K'. Calcium is represented by 'Ca', Iron by 'Fe', and Sodium by 'Na'.

The correct chemical symbol for Calcium is CA. It is important to distinguish between the various chemical elements based on their symbols for accurate scientific communication.
