what is oxygen in the periodic table?

Oxygen is element No. 8 on the Periodic Table of Elements. ... Element No. 8 on the Periodic Table of the Elements is a colorless gas that makes up 21 percent of Earth's atmosphere. Because it's all around, oxygen is easy to dismiss as dull and inert; in fact, it's the most reactive of the non-metallic elements.

Isotopes are elements that contain the same amount of protons, but differ in the number of neutrons in their nuclei. ... Therefore, oxygen 16 has 8 protons and 8 neutrons, oxygen 17 has 8 protons and 9 neutrons, and oxygen 18 has 8 protons and 10 neutrons.

By bonding with two hydrogen atoms, oxygen has its 6 outer shell electrons + 2 shared electrons from the hydrogen making 8 (and a filled shell makes a happy atom. Each of the hydrogen atoms has their 1 electron + 1 shared electron to fill their shell with 2 electrons.

The number of protons and the number of electrons are always the same in an element that is neutral and has no charge. Therefore oxygen has 8 electrons. You will find that the atomic weight of oxygen is about 16.

At standard temperature and pressure (STP), two atoms of the element bind to form dioxygen, a colorless, odorless, tasteless diatomic gas with the formula O2. Oxygen is a member of the chalcogen group on the periodic table and is a highly reactive nonmetallic element.

Free elemental oxygen occurs naturally as a gas in the form of diatomic molecules, O2 (g). Oxygen exhibits many unique physical and chemical properties. For example, oxygen is a colorless and odorless gas, with a density greater than that of air, and a very low solubility in water.

In this Lewis structure of the hydronium ion, oxygen is sharing 3 of its valence electrons in covalent bonds with hydrogen and there is a single pair of unshared electrons. 3 + 2 = 5. Oxygen is in periodic table group VIA and has 6 valence electrons in its natural state.
1166676
Oxygen is an element. It is made up of one kind of atom. ... Since oxygen atoms or oxygen gas is made up of only one substance it is not a mixture it is a pure substance.

So how many electrons are in the outermost shell? You have six electrons here. So oxygen has six valence, valence electrons.

Oxygen with the symbol O has the atomic number 8 which means it is the 8th element in the table. The number eight also means that oxygen has eight protons in the nucleus. The number of protons and the number of electrons are always the same in an element that is neutral and has no charge.

The number of protons and the number of electrons are always the same in an element that is neutral and has no charge. Therefore oxygen has 8 electrons.

Atomic and Molecular Weights Thus, oxygen was assigned an atomic mass of 16. We now know that a hydrogen atom has a mass of 1.6735 x 10-24 grams, and that the oxygen atom has a mass of 2.6561 X 10-23 grams.

An oxide (/ˈɒksaɪd/) is a chemical compound that contains at least one oxygen atom and one other element in its chemical formula. "Oxide" itself is the dianion of oxygen, an O2– atom. Metal oxides thus typically contain an anion of oxygen in the oxidation state of −2.

oxygen-17 has 8 protons and electrons. # neutrons = mass # - #protons. So, in oxygen-17, # neutrons = 17 - 8 or 9.

Oxygen typically has 4 non-bonding electrons (or 2 lone pairs). The full valence shell for oxygen is 8 and the number of electrons in bonds is 4.
