## Does carbon have a high atomic mass?

On the periodic table the mass of carbon is reported as 12.01 amu. This is the average atomic mass of carbon. No single carbon atom has a mass of 12.01 amu, but in a handful of C atoms the average mass of the carbon atoms is 12.01 amu….

Isotope Atomic Mass amu Natural Abundance %

Why does Co have a greater atomic mass than nickel?

Cobalt has 27 protons while Nickel has 28 – thus Cobalt is first on the table. Atomic mass, however, has to do with protons and neutrons. * The weighted average of Cobalt’s isotopes is slightly larger than that of Nickel’s isotopes, so its atomic mass is higher despite having fewer protons.

### How is the atomic mass of carbon or any other element determined?

Atomic mass is based on a relative scale and the mass of 12C (carbon twelve) is defined as 12 amu; so, this is an exact number. Each carbon atom has the same number of protons and electrons, 6. 12C has 6 neutrons, 13C has 7 neutrons, and 14C has 8 neutrons and so on.

### What is the atomic mass of carbon in Brainly?

Answer Expert Verified Atomic mass of carbon (C) 12 u. Atomic mass of some common elements : Hydrogen (H) → 1 u.

What is the atomic mass of nickel?

58.6934 u
Nickel/Atomic mass

What is the atomic mass of cobalt and nickel?

The relative atomic masses of nickel, cobalt, and iron are 58.70, 58.9332 and 55.847, respectively, which element has the greatest mass?

#### Why does cobalt have a higher atomic mass than nickel?

So, while the details of that article may be out of date, the reason cobalt has a higher natural abundance atomic mass than nickel is a combination of nuclear stability and stellar processes. See On the e-process – Its components and their neutron excesses for further discussion of natural abundance ratios of Co and Ni isotopes.

#### Which is the average mass of an element?

Atomic Masses. The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D).

Which is the most stable isotope cobalt or nickel?

In that case, wouldn’t it be the most stable for both atoms to mainly be found with 28 neutrons; and so, cobalt-55 and nickel-56 would be the most stable isotopes of each element. Why is that not the case? Am I missing or misunderstanding something?

Which is the most abundant chemical element in the universe?

Its monatomic form (H) is the most abundant chemical substance in the Universe, constituting roughly 75% of all baryonic mass. Helium is a chemical element with atomic number 2 which means there are 2 protons and 2 electrons in the atomic structure. The chemical symbol for Helium is He.
