In the chemical shorthand 14c the fourteen represents the number of?
The 14 in 14C represents the total number of protons and neutrons in the carbon atom's nucleus. Carbon-14 (14C) is a radioactive isotope with 6 protons and 8 neutrons.
An isotope of chlorine has 17 protons and 17 neutrons what is the mass number of that isotope of chlorine?
17 plus 17 equals 34. However, Chlorine-34 does not exist; the stable isotopes are Chlorine-35 and Chlorine-37.
How many proton mg2 plus have?
The number of protons is 12, the number of electrons is 10, the number of neutrons is different for each isotope.
An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the mass number of the xenon isotope?
The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
How many protons neutrons electrons in zinc2 plus?
The number of protons is 30, the number of electrons is 28, the number of neutrons is different for each isotope.
How is atomic number differ from mass number?
atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
Why can you subtract the atomic number from the atomic mass and get the number of neutrons?
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
Is the mass number the number of protons and neutrons?
No, The atomic mass is the number of protons plus the number of neutrons (the mass of the atom's nucleus). Note that the atomic mass is therefore different in cases where there are different isotopes of the element (because the nucleus will have a different number of neutrons for each isotope). The atomic number is the number of protons (or electrons in the atom's neutral state).
How many protons and neutrons in francium?
Francium has 87 positively charged protons and 87 negatively charged electrons, plus a varying number of uncharged neutrons, of which 136 is the commonest amount. Number of neutrons = Atomic mass of the isotope - 87
How many protons neutrons and electrons does Mg plus have?
Magnesium has 12 protons and electrons and 12, 13 or 14 neutrons, depending on the isotope.
What equals the number of neutrons plus the number of protons in an atom?
The sum of the number of protons and neutrons in an atom is known as the atomic mass. It is equivalent to the mass number of the atom, which represents the total number of protons and neutrons in the nucleus.
