What element is an atom that has 8 protons?

oxygen
On the periodic table of elements, oxygen is represented by the symbol O. It has an atomic number of 8 because it has 8 protons in its nucleus.

### How many electrons are there in an atom with 8 protons?

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.

What element has 8 electrons 8 protons and 8 neutrons?

Oxygen
Oxygen has eight protons, eight neutrons, and eight electrons. Oxygen is different from carbon because it has more particles.

How many protons are in an element with an atomic number of 8 and a mass of 18?

The number of protons is 8 and neutrons are 10 in an atom of mass number 18. Hence, there are 8 protons and 10 neutrons in an atom of mass number 18 and 8 electrons.

## What is the element with 8 electrons?

Oxygen is the eighth element in the periodic table, with the symbol O. This means that it has eight electrons in its neutral state.

Does 8 protons have 8 neutrons?

An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.

What element has a neutron of 8?

oxygen atom
Answer 8: An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999.

### What element has 8 protons 8 neutrons and 9 electrons?

8 17 This isotope of oxygen has 8 protons (atomic number), 8 electrons and 9 neutrons. (Recall that mass number is the total of protons and neutrons. )

How many protons neutrons and electrons are in a neutral atom with an atomic number of 8 and a mass number of 16?

Answer 8: An oxygen atom usually has 8 protons, 8 neutrons, and 8 electrons. Looking at the periodic table, oxygen has atomic number 8 and atomic weight 15.999. The atomic number tells you how many protons are in the atom’s nucleus.

How do you find number of protons?

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules.

1. The number of protons in the nucleus of the atom is equal to the atomic number (Z).
2. The number of electrons in a neutral atom is equal to the number of protons.
