# What is a gas with 8 protons and 8 electrons?

## What is a gas with 8 protons and 8 electrons?

Oxygen
Oxygen is #8 in the periodic table. That means it has 8 protons and 8 electrons.

### What element has a proton of 8?

Oxygen with the symbol O has the atomic number 8 which means it is the 8th element in the table. The number eight also means that oxygen has eight protons in the nucleus. The number of protons and the number of electrons are always the same in an element that is neutral and has no charge.

Is 8 protons and 8 neutrons an isotope?

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 are the 8 noble gases?

Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

## What element is a gas with 8 protons and 8 neutrons?

OXYGEN
OXYGEN – I am a gas with 8 protons and 8 neutrons.

### What is the atomic mass of 8 protons and 8 neutrons?

Explanation: Since oxygen has 8 protons and 8 neutrons, the atomic mass of oxygen is 16, which is the sum of protons and neutrons.

What gas has 8 neutrons?

What is the mass of 8 protons and 8 neutrons?

Since oxygen has 8 protons and 8 neutrons, the atomic mass of oxygen is 16, which is the sum of protons and neutrons.

## What are noble gases Class 9?

The noble gases, also known as the inert gases and the aerogens, are the elements that belong to group 18 of the modern periodic table. The elements that belong to this group are: Helium (He) Neon (Ne)

### What are noble gases give two example?

noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

What does 15.999 mean in oxygen?

Correct! Oxygen is a non-metal with an atomic mass of 15.999. Oxygen’s atomic number is 8. It is a colorless, tasteless and odorless element that consitutes 21% of the atmosphere. Oxygen is a non-metal which means that it is not easily able to conduct electricty or heat and does not reflect light.

What is the atomic number of an element with 8 protons 9 neutrons and 8 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. ) Isotopes are also often written as C-12 C-13 C-14 The number is the mass number.
