In one atom of the oxygen-17 isotope, there are eight protons, nine neutrons, and eight electrons. The number of protons will be the same for every oxygen …
• ## Why does oxygen-17 have 9 neutrons?

Oxygen is atomic number 8, which means it must have 8 protons, and 8 electrons. That leaves 9 neutrons to make up the isotope number of 17. That is how it works.

## How many neutrons does oxygen-18 have?

“Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.

## How many protons electrons and neutrons are in oxygen-17 and oxygen-18?

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.

## What is oxygen-17 atomic number?

Answer and Explanation: The atomic number of oxygen-17 is 8. The atomic number is equal to the number of protons in an element and can be found by locating the element on the periodic table. The atomic number is listed in the upper left corner of the element’s symbol.

## How many protons electrons and neutrons are in oxygen-17?

Solution: Cl-have 17 protons, 18 neutrons and 18 electrons.

## What has 17 protons and 18 electrons and 18 neutrons?

All oxygen atoms have 8 protons, but the nucleus might contain 8, 9, or 10 neutrons. “Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.

## How many neutrons are in oxygen-18?

Answer and Explanation: Oxygen-17 and oxygen-18 are related in that they both contain exactly eight protons in their nuclei.

## How many neutrons does oxygen-17 have?

Some oxygen atoms have 9 neutrons, while others have 10 neutrons.

## Does oxygen have 9 neutrons?

In an oxygen atom, there are 8 protons and 8 electrons. Most oxygen atoms also have 8 neutrons, but it is possible for an oxygen atom to have 9 or 10 neutrons. They are just rarer. The oxygen we breathe is not in atomic form.

## Why oxygen has 8 protons and why it can’t have 9 neutrons?

Another isotope of oxygen has 9 neutrons. This isotope is oxygen-17.

## How many protons electrons and neutrons are in oxygen-17 and oxygen-18?

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.

## What is the mass number of oxygen-17?

Oxygen-17 atom is the stable isotope of oxygen with relative atomic mass 16.999131.

## Why is the mass number of oxygen-17?

Oxygen atoms with 8 neutrons would have a mass number of 16 (8 p+ + 8 n0), meaning they would have a mass of about 16 amu. Some oxygen atoms have 9 neutrons, while others have 10 neutrons. Oxygen atoms with 9 neutrons would have a mass number of 17 (8 p+ + 9 n0), meaning they would have a mass of about 17 amu.

## What is atomic number of oxygen-18?

Looking at the nuclide symbol for oxygen-18, we can recognize that O is the chemical symbol of oxygen, 18 is the mass number, and eight is the atomic number.

## How many neutrons is oxygen 18?

“Light” oxygen-16, with 8 protons and 8 neutrons, is the most common isotope found in nature, followed by much lesser amounts of “heavy” oxygen-18, with 8 protons and 10 neutrons.

## How many electrons does oxygen 18 have?

A neutral atom of oxygen-18 will have 8 electrons. The way to determine this is to look at the atomic number of oxygen, which is 8. This means that all oxygen atoms have 8 protons in their nuclei. This is true for all isotopes of oxygen as well.

## How many neutrons does 18 have?

We can substitute these into the equation and solve for the number of neutrons. Subtracting eight from both sides of the equation tells us that there are 10 neutrons in atoms of oxygen-18.
