To be an isotope stable, the number of neutrons should not exceed 1.5 times than protons.
No, there are actually 2 protons and 2 neutrons in the helium-4 isotope. The number of protons determines the element, while the sum of protons and neutrons gives the atomic mass of an isotope.
Isotope 24Na (or Na-24) has 11 protons and 13 neutrons, its mass number is 24Isotope 23Na is the stable form of Na with 11 protons, 12 neutrons and with mass number 23.
Boron has 5 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a boron isotope = Mass number - 5
protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.
Protons = 17; Electrons = 17; Neutrons = 19
To be an isotope stable, the number of neutrons should not exceed 1.5 times than protons.
Sulfur-31 is the isotope with 16 protons and 15 neutrons.
The isotope that has 13 protons and 14 neutrons is aluminum.
No, there are actually 2 protons and 2 neutrons in the helium-4 isotope. The number of protons determines the element, while the sum of protons and neutrons gives the atomic mass of an isotope.
Isotope 24Na (or Na-24) has 11 protons and 13 neutrons, its mass number is 24Isotope 23Na is the stable form of Na with 11 protons, 12 neutrons and with mass number 23.
An isotope of Nitrogen shows 7 protons & 8 neutrons.
oxygen has 8 protons as its atomic number is 8. The number of neutrons depends on the isotope. O-15 isotope will have 7 neutrons, O-16 isotope will have 8 neutrons. (Note: Mass number = Number of protons + number of neutrons)
An element is defined by the number of protons in the nucleus; for example, carbon always has 6 protons. Elements can also have different numbers of neutrons in the atomic nucleus, and each number of neutrons gives you a different isotope. So, there is the isotope called carbon 12, with 6 neutrons (12 nuclear particles in total) and there is also the isotope called carbon 14, with 8 neutrons (14 nuclear particles in total). Every element has a number of isotopes.
16 protons 20 neutrons
A nitrogen atom has 7 protons, 7 electrons and 7 neutrons for the most common isotope
Promethium has 61 protons and electrons.For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
