Isotopes have same atomic no. but different atomic mass due to presence of extra neutrons in the nucleus
The atomic mass is calculated by averaging the masses of the isotopes based on their abundance. In this case, 75% of the isotopes have a mass of 35.0 amu and 25% have a mass of 37.0 amu. Atomic mass = (0.75 * 35.0 amu) + (0.25 * 37.0 amu) = 35.5 amu.
Tin has 10 isotopes, with the following mass numbers, masses, and abundances:112 - 111.9403 amu - 0.95%114 - 113.9395 amu - 0,65%115 - 114..9400 amu - 0.34%116 - 115.9390 amu - 14.24%117 - 116.9402 amu - 7.57%118 - 117.9393 amu - 24.01%119 - 118.9410 amu - 8.58%120 - 119.9401 amu - 32.97%122 - 121.9421 amu - 4.71%124 - 123.9445 amu - 5.98%
False. Carbon-12 and carbon-14 are isotopes of carbon that differ in the number of neutrons in their nuclei, not electrons. Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. The number of electrons in an atom is determined by its atomic number, which is the same for both isotopes of carbon (6 electrons).
The element with isotopes of approximately 10 amu and 11 amu is boron (B) on the periodic table. Its isotopes include Boron-10 and Boron-11.
One example of isotopes is carbon-12 (12C) and carbon-14 (14C). These isotopes have the same number of protons, but different numbers of neutrons. Carbon-12 is stable and commonly found in nature, while carbon-14 is radioactive and used for carbon dating.
The atomic mass is calculated by averaging the masses of the isotopes based on their abundance. In this case, 75% of the isotopes have a mass of 35.0 amu and 25% have a mass of 37.0 amu. Atomic mass = (0.75 * 35.0 amu) + (0.25 * 37.0 amu) = 35.5 amu.
Coal, charcoal, and diamond are not isotopes of carbon; they are forms of carbon but are not considered isotopes. Fluorine is a different element and not related to carbon. Isotopes of carbon include carbon-12, carbon-13, and carbon-14.

All isotopes of carbon have the same number of protons and electrons; but they have a different number of neutrons.
Carbon and nitrogen isotopes are not isotopes of each other. They are different elements with their own set of isotopes. Carbon isotopes include carbon-12, carbon-13, and carbon-14, while nitrogen isotopes include nitrogen-14 and nitrogen-15.
Yes Carbon 12, Carbon 13 and Carbon 14 are isotopes of carbon. Diamond and graphite are allotropes.
mass nummbers
Yes, diamond and graphite are isotopes of carbon as they are both entirely made of carbon. However they have very different structures resulting in their different properties.
Many elements have different isotopes: 1) Carbon - Carbon 12, Carbon 14 2) Hydrogen - Protium, Deuterium, Tritium 3) Chlorine - Chlorine 35, Chlorine 37 etc
The atomic mass of the element cannot be discovered with the given information. It was not specified as to the ratio of the isotopes of the element. If they two isotopes are equally represented, then it's half the sum of the masses of the two isotopes, which is 63 + 65 = 128, and 128 / 2 = 64 amu.If another ratio (or perhaps a percentage) of the isotopes if given, then a calculation can be made to discover the atomic mass of the element. This calculation will reflect the different amounts of the two isotopes present in samples of that element.Added:Though the answer given here is correct for the question stated above, there is a more clearing answer for the suggested question: Which element has two isotopes .... (etc.). This is typically true for copper, Cu, atom no. 29, of which two natural occurring isotopes exist:Cu-63, mass 62.92960 a.m.u., occurrence 69.1%Cu-65, mass 64.92779 a.m.u., occurrence 30.9%The average (relative) atomic mass = 63.55
They are called isotopes. eg we have different isotopes of carbon
False. Carbon-12 and carbon-14 are isotopes of carbon that differ in the number of neutrons in their nuclei, not electrons. Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. The number of electrons in an atom is determined by its atomic number, which is the same for both isotopes of carbon (6 electrons).
