Now you can figure out how many electrons, protons and neutrons Oxygen has: Atomic number (which is always the smaller of the two numbers) is 8. Hence 8 protons. Because the atom is neutral, there are also 8 electrons.

8

Because protons and neutrons are roughly equal in mass, an isotope’s number is equal to the sum of its protons and neutrons. 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.

Which statement is true about oxygen-17 and oxygen-18? They do not have the same number of protons. Their atoms have an identical mass. They are isotopes of oxygen.

The difference is that the atoms of oxygen-16 have 8 neutrons but the atoms of oxygen-17 contains 9 neutrons inside their nuclei.

The neutron flux slowly converts 16O in the cooling water to 17O by neutron capture, increasing its concentration. The neutron flux slowly converts 17O in the cooling water to carbon-14, an undesirable product that escapes to the environment….Oxygen-17.

Oxygen-17 (17O) is now being used for diagnostic applications and medical research to create a new generation of NMR Images. New developments with 17O enhance the quality of information about living tissue to improve the practice of medicine in the fields of cardiology and neurology among others.

Oxygen-16 and oxygen-18 differ in the number of neutrons in their nuclei. Oxygen-16 has 8 neutrons, while oxygen-18 has 10 neutrons.

Explanation: For oxygen, Z , the atomic number =8 . There are 8 protons in its nucleus (and protons are positively charged particles). To balance this charge (the atom is electrically neutral after all), the oxygen nucleus is surrounded by 8 negatively charged electrons.

An atom containing one proton is a hydrogen atom (H). An atom containing 6 protons is a carbon atom. And an atom containing 8 protons is an oxygen atom. Thus, if an atom contains equal numbers of protons and electrons, the atom is described as being electrically neutral.

When an element loses electrons it commonly does so until all valence electrons are gone; thus, magnesium with 2 valence electrons will react to become Mg2+, magnesium cation by losing the 2 valence electrons.

Magnesium, Mg Magnesium is in Group 2. It has two electrons in its outer shell. When these electrons are lost, a magnesium ion, Mg 2+, is formed. A magnesium ion has the same electronic structure as a neon atom (Ne).
