Nitrogen is an atomic element because it exists as individual nitrogen atoms in its elemental form. It is a diatomic molecule consisting of two nitrogen atoms bonded together when it is in its gaseous state.
Gold is not a molecular element. It is a pure chemical element with the atomic number 79 and symbol Au. Its atoms are composed of 79 protons and varying numbers of neutrons in the nucleus, surrounded by electrons.
Tungsten is an atomic element, meaning it consists of individual tungsten atoms. Tungsten forms metallic bonds, rather than ionic or molecular bonds, due to its electron configuration.
No, sodium is not a molecular element. It is a chemical element with the symbol Na and atomic number 11. In its pure form, it exists as single atoms, not molecules.
An element is considered atomic if it consists of individual atoms. A molecule, on the other hand, consists of two or more atoms chemically bonded together. If an element exists as individual atoms (like Helium), it is atomic; if it exists as molecules (like Oxygen as O2), it is molecular.
The molecular formula for argon is Ar. Argon is a noble gas with atomic number 18 and does not typically form molecules like other elements.
