How is the mass number related to the number of protons and neutrons and atoms has?
The mass number of an element is equal to the number of protons plus the number of neutrons.
Is the mass of a hydrogen atom different from the mass of an oxygen atom?
all atoms have different masses Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.
Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
What is the relationship between mass number and atomic numbers?
Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Mass number is the number of protons and neutrons in the nuclei of the atoms of a specific isotope of an element.
What are two atoms called when they have different number of protons?
The atomic number is the number of protons, so in this case it is 2, which is Helium. The charge or ionization of the atom is the difference between the number of protons and the number of electrons; in this case, they are the same, so the atom is neutral (not ionized). The atomic mass number is the sum of the protons and neutrons, so in this case 4. Thus, you have a non-ionized atom of Helium-4.
What are atoms that have different masses but the number of protons?
Atoms that have different mass numbers but the [same] number of protons are called isotopes.
Isotopes are atoms that have the same number of protons but a different?
Isotopes are atoms of a given element that have the same number of protons but a different mass number and therefore a different number of neutrons.
What's the difference between an atomic number in the mass number of an Atom?
All the atoms of a particular element have the same atomic number (number of protons). The atoms of different elements have different numbers of protons. For example, all oxygen atoms have 8 protons and all sodium atoms have 11 protons. The mass number of an atom is the total number of protons and neutrons it contains.
Do isotopes have the same atomic number and different mass numbers?
Yes. Isotopes have the same atomic number because all of their atoms have the same number of protons. They have different mass numbers because their atoms have different numbers of neutrons, and mass number is the sum of the numbers of protons and neutrons.
Why do all atoms have a different number of protons?
Dear questioner,As an answer to your question I should mention there are atoms which have the same number of protons but are considered different. These atoms are called Isotopes. Isotopes of an element have the same number of protons but the number of Neutrons are not the same. Isotopes have the same chemical virtues but in the physical virtues related to mass they are a bit different.
Do atoms of the same number have a different mass number?
Atoms of the same atomic number (= number of protons in each nucleus) can have different mass numbers because of containing different numbers of neutrons in each atom.
What is an atoms mass number?
neutrons + protons = mass number
Explain Atomic number and mass number - what are these different atoms called?
We make atomic number by number of protons in a atom. We make mass number by total of both protons and neutrons.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
What Make up 50 percent of the atomic mass of the nucleus?
Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons. Heavier atoms have a larger percentage of their mass in neutrons.Well, this is not exact, but smaller atoms have about the same number (and mass) of neutrons and of protons.

What is the number of protons in the nucleus of an atoms atomic?
The sum of protons and neutrons in the atomic nucleus is called "mass number"; this value is different for each isotope.
How are atomic mass and atomic number different?
Atomic number is the number of protons in the nuclei of the atoms of an element. Atomic number is unique to each element. Atomic Mass is the combined mass of the protons, neutrons, and electrons in an atom of an element.
