What isotope has a mass number of 24?
magnesium isotopes
There are 12 protons in all magnesium isotopes. The isotope whose atomic weight is 23.985 amu has a mass number of 24 (protons and neutrons), so 24 – 12 protons gives 12 neutrons. The symbol for this isotope is 24Mg.
What symbol contains 28 protons and 30 neutrons?
Nickel atoms have 28 electrons and 28 protons with 30 neutrons in the most abundant isotope. Under standard conditions nickel is a silvery-white metal that is fairly hard, but malleable.
How many protons neutrons and electrons does Fe 54 have?
Iron-54 is composed of 26 protons, 28 neutrons, and 26 electrons.
What isotope has 53 protons and 78 neutrons?
Iodine-131
Iodine-131 has 131 minus 53 protons = 78 neutrons.
What isotope contains 24 protons 31 neutrons and 24 electrons?
Chemical Elements.com – Chromium (Cr)

Properties of Nickel-58 Isotope:
| Properties of Nickel-58 Isotope: | NICKEL-58 |
|---|---|
| Atomic Number (Z) | 28 |
| Mass Number (A) | 58 |
| Nucleon Number (A) | 58 |
| Proton Number (Z) | 28 |
How do you find the isotope of an element?
Subtract the atomic number (the number of protons) from the rounded atomic weight. This gives you the number of neutrons in the most common isotope. Use the interactive periodic table at The Berkeley Laboratory Isotopes Project to find what other isotopes of that element exist.
What element has 24 protons and 52 mass number?
Chromium 52
Chromium 52: The atomic number Z = 24, so there are 24 protons and 24 electrons. The mass number A = 52.
How many protons are in mg 24?
For instance, 24Mg is read as “magnesium 24,” and can be written as “magnesium-24” or “Mg-24.” 25Mg is read as “magnesium 25,” and can be written as “magnesium-25” or “Mg-25.” All magnesium atoms have 12 protons in their nucleus.
How many protons and electrons are in an isotope?
17 protons. 17 electrons. 35 – 17 = 18 neutrons. Isotopes are atoms of an element with the normal number of protons and electrons, but different numbers of neutrons. Isotopes have the same atomic number, but different mass numbers.
How to find the mass of an isotope of carbon?
From the periodic table, we see that the atomic number (number of protons) for the element carbon is 6. The name carbon-14 tells us that this isotope’s mass number is 14. The chemical symbol for carbon is C. Now write the isotopic notation for carbon-14. We can determine the number of neutrons as 14 −6 = 8 neutrons.
What is the chemical notation for the isotope carbon 14?
Example 1: What is the isotopic notation for the isotope carbon-14? From the periodic table, we see that the atomic number (number of protons) for the element carbon is 6. The name carbon-14 tells us that this isotope’s mass number is 14. The chemical symbol for carbon is C.
Why is Isotope Notation important in nuclear chemistry?
Isotope notation, also known as nuclear notation, is important because it allows us to use a visual symbol to easily determine an isotope’s mass number, atomic number, and to determine the number of neutrons and protons in the nucleus without having to use a lot of words. Additionally, N = A −Z.
