What number is written after the isotope when writing the name?
The atomic mass number of that isotope. So C14 has a molecular mass of 14 grams/mole U238, 238 grams/mole
What is the Relative atomic mass of chromium?
Chromium is a meta element. Atomic mass of it is 52.
How is atomic mass number calculated?
There are a few ways to determine the mass number, depending on what information you have about the isotope: 1. The mass number is calculated as the sum of an isotope's protons and neutrons. 2. The name of an isotope generally includes the mass number. For instance, carbon-14 has a mass number of 14. 3. The atomic mass (aka isotope mass or atomic weight) rounded to the nearest whole number is the mass number.
What is the top number in an isotope?
An isotope is identified by atomic number (element number or name), by mass number, and by atomic weight. The mass numberfor an isotope is listed as a leading superscript such as 29Si, which in this example is silicon containing 14 protons and 15 neutrons (a rarer but stable isotope of the element). Similarly the atomic weight is indicated by a superscript such as U235 , an isotope of uranium having 92 protons and 143 neutrons.The actual atomic weight is often expressed as a decimal number corresponding to the mass of the atom in "atomic units", where a proton is about 1.0072, a neutron 1.0086, and an electron about .00055 atomic units.
When an isotope undergoes alpha decay which of the following change A The name of the element B The atomic number C The mass number D All of these change?
D. All of these change. In alpha decay, an isotope emits an alpha particle, which consists of two protons and two neutrons, leading to a decrease in the atomic number and mass number of the parent isotope. This results in the formation of a new element with a different name, atomic number, and mass number.

What is the atomic number of carbon 14?
Carbon is a non metal element. Atomic mass number of it is 12.
The atomic number of carbon is 6 the atomic number of nitrogen is 7 the atomic number of oxygen is 8 name the isotope represented by the drawing?
The isotope represented by the drawing is Carbon-13. This isotope has 6 protons and 7 neutrons in its nucleus, giving it a total atomic mass of 13.
What are the atomic number and atomic mass of the isotope Br 79?
The atomic number of any bromine atom is 35, and the atomic mass number is the number stated after the element name in the question, in this instance 79.
What is the name and atomic symbol of an isotope with the mass number of 214 and 131 neutrons?
The proton number of this element is 214 - 131 = 83 protons Look this number up in the periodic table. You will see that the element is Bismuth.
How is the mass number of an isotope expressed in the name of an atom?
The mass number is the sum of protons and neutrons in the atomic nucleus. If you think to a name as uranium-238 the meaning is that the nucleus has 238 p+n.
