This certain isotope of oxygen would have a mass of about 18 because electrons weigh almost nothing.
Protons: 21 Neutrons: 29 Electrons: Normally 21
no. an atom is made up of protons neutrons and electrons. protons have a charge of plus one electrons have a charge of minus one neutrons have no charge. therefore the number of protons and electrons must be equal (balancing the charges) for the atom to be neutral. ;)
It would likely have 6 neutrons which means it would have a mass of 12, hence Carbon-12, the most abundant isotope of C. If it had 8 neutrons (Carbon-14), it would be unstable and would decay by negative beta decay to stable Nitrogen-14, the most abundant isotope of N which has 7 protons and 7 neutons for a mass of 14.
All atoms of an element have the same number of protons and electrons (in the neutral state).
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
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
No. The number of neutrons has no affect on the number of protons and electrons.
Promethium has 61 protons and electrons; For each isotope the number of neutrons is different. Number of neutrons = Mass number of an isotope - 61
Nickel has 28 electrons and protons; the number of neutrons is specific for each isotope. Number of neutrons in a nickel isotope = Mass number -28
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons.
Americium has 95 protons and electrons. Number of neutrons: Atomic Mass of an isotope - number of protons
Technetium has 43 protons and 43 electrons. For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
Protactinium has 91 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic Mass of the isotope - 91
Technetium has 43 protons and 43 electrons. For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
An isotope is an element with the same number of electrons and protons different number of neutrons.
There are 7 protrons, 7 electrons and 7 electrons in an atom of nitrogen.
