# How many proton neutrons and electrons are in oxygen?

## How many proton neutrons and electrons are in oxygen?

Oxygen has eight protons, eight neutrons, and eight electrons. Oxygen is different from carbon because it has more particles. Each kind of atom has a different number of the three particles. Protons and neutrons are in the center, or nucleus, of the atom.

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

Oxygen-18 is composed of 8 protons, 10 neutrons, and 8 electrons.

How many electrons are present in 40ca2 +?

Ca and 40Ca2+ both have 20 protons. Ca has 20 electrons. Ca2+ has 18 electrons. The +2 charge on 40Ca2+ indicates that 40Ca2+ has 2 less electrons than 40Ca.

### How many neutrons are in o2?

### How many protons neutrons and electrons are there in an atom of O 17?

Oxygen-17 has 8 protons, 8 electrons, and 9 neutrons.

How many electrons are there in o2?

2, 6Oxygen / Electrons per shell

#### How many neutrons are in O 18?

10 neutrons
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.

#### How many electrons does O 18 have?

Answer and Explanation: 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.

How many protons and electrons are present in o2 -? Group of answer choices?

Answer 8: An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons.

## How many electrons are present in o2?

8 electrons
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.

## How many electrons are in a o2?

How many neutrons are in o 17?

9 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.

### How many electrons does an atom of 17 o contain?

Answer and Explanation: In one atom of the oxygen-17 isotope, there are eight protons, nine neutrons, and eight electrons.

### How many electrons are there in o2 -?

How many neutrons are in oxygen 18?

#### How many protons and neutrons does an isotope O 17 has?

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.

#### How many neutrons are in oxygen 17?

What isotope has 17 electrons and 18 neutrons?

A chlorine atom has 17 protons, 18 neutrons, and 17 electrons.

## What has 17 protons and 18 neutrons?

Answer and Explanation: Chlorine-35 has 17 protons and 18 neutrons. It’s considered a stable isotope and is the most abundant isotope of chlorine, with approximately 76%…

## How many protons electrons and neutrons does oxygen have?

Oxygen has a mass number of 16.00 with atomic number 8 which means there are 8 electrons and 8 protons. The number of neutrons is always equal to the mass number- the atomic number.

What is the atomic mass and atomic number of oxygen?

●The atomic number of oxygen is the number of protons in oxygen’s nucleus. ●The atomic mass of oxygen is the average number of protons plus neutrons of all the isotopes of oxygen. ●The Masss number of oxygen is the number of protons plus neutrons of a specific isotope of oxygen.

### What happens if an atom has 9 protons?

For example, if an atom has 9 protons, it will no longer be oxygen, but will instead be Fluorine. Any atom that doesn’t have 8 protons is not oxygen. The amount of electrons must be the same as the number of protons in the atom for it to be neutrally charged.

### What is the electron configuration of oxygen?

Electron configuration of Oxygen is [He] 2s2 2p4. Possible oxidation states are -2. Oxygen is too chemically reactive to remain a free element in air without being continuously replenished by the photosynthetic action of living organisms.
