Group Number: 16. Oxygen has an atomic number of 8. Group Name: Chalcogen. Oxygen, atomic. The chemical element oxygen is a highly reactive non-metal. Oxygen is a chemical element with atomic number 8 which means there are 8 protons and 8 electrons in the atomic structure. The properties of the diatomic form suggest that six electrons bond the atoms and two electrons remain unpaired, accounting for the paramagnetism of oxygen. After hydrogen and helium it is the third most abundant element in the universe. Oxygen is a colourless, odourless reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.

This popular publisher name is Los Angeles Times, if we say the full name. Photooxygen. Element Oxygen (O), Group 16, Atomic Number 8, p-block, Mass 15.999. Are you looking for the right answer? More commonly, the isotope symbol already tells you the atomic number. Given an atomic number (Z) and mass number (A), you can find the number of protons, neutrons, and electrons in a neutral atom. In the periodic table of elements, oxygen is a p-block element and it belongs to group 16 and period 2. For example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4). Relative isotope-ratio measurements of oxygen in water and many other substances commonly are expressedrelative to VSMOW reference material, in which case the δ18O value of VSMOW is 0 ‰ by definition. Oxygen Oxygen is a chemical element with symbol O and atomic number 8. In gaseous appearance, it is colorless and in the liquid and solid state, it is pale blue in color. Period Number: 2. 17778-80-2. 17O. 17.999 159 613(5) [0.001 87, 0.002 22] Two major sources of oxygen are air and water. For example, if an atom has 9 protons, it will no longer be oxygen, but will instead be Fluorine. 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 as well as with other compounds. Its symbol is O. However,two other scales have been used commonly: (1) in … We solved this Oxygen's atomic number crossword clue. Melting Point: 54.36 K (-218.79°C or -361.82°F) Boiling Point: 90.20 K (-182.95°C or -297.31°F) Density: 0.001429 grams per cubic centimeter. The atomic number is the smaller of the two numbers in the symbol. Oxygen (after hydrogen and helium) is the third most abundant element in the universe. Atomic Weight: 15.9994. What's in a name? For example, if the symbol is written as 14 6 C, the number "6" is listed. Our team found this clue in LA Times Daily Crossword and gave the correct solution.
