What is the atomic mass of oxygen 17?
16.999131Description: Oxygen-17 atom is the stable isotope of oxygen with relative atomic mass 16.999131.
The least abundant (0.038 atom percent) isotope of naturally occurring oxygen..
Is oxygen 18 radioactive?
Oxygen isotope species Stable isotopes are variants of atoms that differ in mass but do not decay over time, that is, they are not radioactive. The element oxygen (O) is found in three naturally occurring stable isotopes, 18O, 17O, and 16O.
What is the difference between oxygen 16 and 18?
Chemical elements are found in different versions, called isotopes. 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.
Why does oxygen have a mass number of 16?
Atomic mass is equal to number of protons + number of neutrons in the atom so in oxygen 8 protons and 8 neutrons are present therefore 8+8=16.
How many electrons are there in oxygen?
2, 6Oxygen/Electrons per shell
Does ice have oxygen?
As a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral. It possesses a regular crystalline structure based on the molecule of water, which consists of a single oxygen atom covalently bonded to two hydrogen atoms, or H–O–H.
Why do nuclei spontaneously decay?
In the case of radioactive decay, instability occurs when there is an imbalance in the number of protons and neutrons in the atomic nucleus. … If the nucleus of an atom is unstable, eventually it will break apart to lose at least some of the particles that make it unstable.
How many energy levels does oxygen have?

What are the 3 stable forms of oxygen?
There are three known stable isotopes of oxygen (8O): 16O, 17O, and 18O. Radioactive isotopes ranging from 11O to 26O have also been characterized, all short-lived.
How many electrons does oxygen 16 have?
8 electronsThe 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.
Why lighter nuclei are unstable?
Unstable Nuclei. … Too many neutrons or protons upset this balance disrupting the binding energy from the strong nuclear forces making the nucleus unstable. An unstable nucleus tries to achieve a balanced state by given off a neutron or proton and this is done via radioactive decay.
Why is it called radioactive?
Originally Answered: Why is radioactivity known as “radioactivity”? The name was given before either nuclei or gamma rays were discovered. It was just a mysterious radiation that some minerals gave off. It radiated, and a small number of minerals showed this activity, so they were called radioactive.
Is oxygen 16 an isotope?
Oxygen-16 (16O) is a stable isotope of oxygen, having 8 neutrons and 8 protons in its nucleus. It has a mass of 15.99491461956 u. Oxygen-16 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen’s natural abundance.
What is the symbol for oxygen 18?

Why even even nuclei are more stable?
Nuclides containing odd numbers of both protons and neutrons are the least stable and this means more radioactive. Nuclides containing even numbers of both protons and neutrons are most stable and this means less radioactive. than nuclides containing even numbers of protons and odd numbers of neutrons.
