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.

1 Answer. Oxygen has 6 valence electrons. A way to remember this is to note that it is in column 16 of the periodic table. For the representative elements (columns 1, 2, 13-18), the digit in the units place of the column number is the same as the number of valence electrons.

Oxygen is a non-metal element and is found naturally as a molecule. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature. A rotating model of an oxygen molecule.

Oxygen is the most abundant element (by mass) in the earth's crust, in ocean water, and in the human body.

As you can see, oxygen has 2 of its 8 electrons in the shell closest to the nucleus, and the remaining 6 electrons - which are called valence electrons - in its second shell - this is oxygen's outermost shell. In order to complete its octet, it needs 8 electrons in its outermost shell.

So, we have a mass of 32 grams. We can also use the periodic table to determine that the Mr of oxygen is 16. So there are 2 moles of Oxygen present.

(Gcsescience.com, 2018) Oxygen is heavier than hydrogen and carbon because of the number of protons, neutrons and electrons. An oxygen atom has 8 protons, 8 neutrons and 8 electrons around the nucleus.

Oxygen has no empty orbitals with it . It only possess orbitals upto 2p which contains 4 electrons. So it cannot expand its octet by exiting it's electrons.

Explanation: Clearly, there are 6 oxygen atoms on the left hand side of the equation; and, equally clearly, there are 6 oxygen atoms on the right hand side of the equation, as indeed there must be in a stoichiometrically balanced equation.

Carbon atoms are made up of 6 protons, 6 electrons, and 6 neutrons, whereas Oxygen atoms are made of 8 protons, 8 neutrons, and 8 electrons. This may not sound like a big difference at the atomic level, but it is responsible for all of the differences between Oxygen and Carbon.

Group 16: Oxygen Group Contains: 3 non-metals, 2 metalloids ● Valence Electrons: 6 ● Reactivity: Reactive ● Other shared properties: ● All but O are solid at room temperature.

So, to reiterate, the difference between oxygen (O) and oxygen (O2) is that the former is an oxygen atom while the latter consists of two O atoms bound together, forming a molecule also called oxygen.

The periodic table (also known as the periodic table of elements) is organized so scientists can quickly discern the properties of individual elements such as their mass, electron number, electron configuration and their unique chemical properties.

An oxygen atom has a nucleus with protons and neutrons, and electrons that orbit around the nucleus. You can make a three-dimensional model of an oxygen atom with round objects; you can use Styrofoam balls, ping-pong balls, rubber balls or golf balls.
