Are nitrogen and oxygen atoms?
The atoms in N2 and O2 are held together by strong covalent bond, sigma bonds and pi bonds. Although molecular nitrogen is very unreactive, it is broken apart in lightning structures and reacts with oxygen atom. We can represent the molecules through electron dot structures or Lewis structures.
What type of atom is an oxygen atom?
Oxygen is a chemical element – a substance that contains only one type of atom. Its official chemical symbol is O, and its atomic number is 8, which means that an oxygen atom has eight protons in its nucleus. Oxygen is a gas at room temperature and has no colour, smell or taste. Oxygen is found naturally as a molecule.
Is oxygen and carbon an atom or molecule?
ELEMENTS are the kinds of atoms that we can have. Carbon is an element, hydrogen is an element, and so is oxygen. (We can call them by their names, or by their symbols – C for carbon, H for hydrogen, and O for oxygen.)
Is nitrogen an atom or molecule?
Nitrogen is a chemical element with an atomic number of 7 (it has seven protons in its nucleus). Molecular nitrogen (N2) is a very common chemical compound in which two nitrogen atoms are tightly bound together. Molecular nitrogen is a colorless, odorless, tasteless, and inert gas at normal temperatures and pressures.
What is carbon, hydrogen oxygen and nitrogen?
CHON is a mnemonic acronym for the four most common elements in living organisms: carbon, hydrogen, oxygen, and nitrogen. In the human body, these four elements compose about 96\% of the weight, and major minerals (macrominerals) and minor minerals (also called trace elements) compose the remainder.
What contains carbon, hydrogen nitrogen and oxygen?
Proteins
Proteins are made of carbon, hydrogen, oxygen, and nitrogen (CHON). Nucleic acids such as DNA and RNA contain carbon, hydrogen, oxygen, nitrogen, and phosphorus (CHON P). The body also needs trace amounts of other elements such as calcium, potassium, and sulfur for proper functioning of muscles, nerves, etc.
What is a carbon oxygen cycle?
: the cycle whereby atmospheric oxygen is converted to carbon dioxide in animal respiration and regenerated by green plants in photosynthesis.
Is nitrogen an atom?

Nitrogen/Atomic number
Nitrogen is a chemical element with an atomic number of 7 (it has seven protons in its nucleus). Molecular nitrogen (N2) is a very common chemical compound in which two nitrogen atoms are tightly bound together. Molecular nitrogen is a colorless, odorless, tasteless, and inert gas at normal temperatures and pressures.
What is hydrogen carbon and nitrogen?
The term CHNOPS is a mnemonic acronym for the six main chemical elements that make up living things. They are carbon (C), hydrogen (H), nitrogen (N), oxygen (O), phosphorus (P) and sulphur (S). As a result, all biological molecules (or biomolecules) contain carbon and hydrogen like lipids.
