it's equal to the difference between atomic number and Atomic Mass number
The statement means that the element in question has three different forms (isotopes) with varying numbers of neutrons in their atomic nuclei. These isotopes of the element share the same number of protons and electrons but have different atomic masses due to the differing number of neutrons.
Iron-59 has 26 protons and 26 neutrons.
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
That statement is incorrect. Argon has an atomic number of 18, which means it has 18 protons in its nucleus. The number of neutrons in an argon nucleus can vary depending on the isotope, but a common isotope, Argon-40, has 22 neutrons.
yes BECAUSE THEY SHOW THAT IN THE PERIODIC TABle SEVERAL THINGS OCCUR THEREFORE I AGREE WITH THIS STATEMENT
I am rational, but not a number. This statement is therefore half correct.
It is equal to the difference between atomic number and Atomic Mass number. A+

Iron-59 has 26 protons and 26 neutrons.
Atomic mass is the total of the number of protons PLUS the number of neutrons.
Atomic mass or mass number.
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
Isotopes describe atoms with the same number of protons and different number of neutrons. These isotopes have the same atomic number but different mass numbers, resulting in variations in atomic mass.
There are only one proton and electron. But it contains 2 neutrons.
Mg has 12 protons since it is element number 12 on the periodic table. To calculate the number of neutrons, subtract the atomic number (12 protons) from the atomic mass (26), which gives 14 neutrons in this case.
That statement is incorrect. Argon has an atomic number of 18, which means it has 18 protons in its nucleus. The number of neutrons in an argon nucleus can vary depending on the isotope, but a common isotope, Argon-40, has 22 neutrons.
