What are the atomic mass of elements rarely whole numbers?
1. First cause: the atomic weight is the sum of the weights of protons, neutrons ans electrons.; they don't have masses as integers.2. Second cause: also occurs the so-called mass defect.Not atomic mass for elements; atomic weight is correct.
Why some elements possess fractional atomic mass?
It is mostly because elements have many isotopes and their average comes to be also fractional.We cannot weigh the atom therefore its atomic mass is fractional.Even elements with only 1 naturally occurring isotope have fractional mass. This is because the nuclear binding energy is a very large (negative) energy, and it shows up in the atomic mass because of the relativistic adjustment that has to be made --E= mc2,
What would cause the average atomic mass to be close to a whole number?
The average atomic mass of an element is close to a whole number when the element has nearly equal amounts of its isotopes, with atomic masses that are close to whole numbers themselves. This occurs in elements with only one stable isotope or with stable isotopes that have similar abundances.
What are the radioactive isotopes?
radioactive isotopes are isotopes with irregular nuclear composition, it emits energy due to decay of atomic nucleus.
What is the pattern of atomic mass as you go across a period?
As you move across a period in the periodic table from left to right, the atomic mass generally increases. This increase is due to the addition of protons and neutrons in the nucleus of the atoms, which raises the overall mass. However, the increase is not perfectly linear, as isotopes and variations in neutron numbers can cause slight fluctuations in atomic mass values.

The various atomic weights of the same element are called?
Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).
What cause different isotopes to have different atomic masses?
Different numbers of neutrons in their nuclei.

Why are most atomic masses a decimal?
The atomic mass of an isotope of an element is the mass of the nucleons (neutrons + protons) in an atom of that isotope. This is nearly, though not exactly, equal to the number of nucleons, and so is nearly a whole number.The main cause for the atomic mass being fractional is that most elements have numerous isotopes, each with a different number of neutrons and so a different atomic mass. The atomic mass for an element is the average of the atomic masses of all its isotopes, weighted together in the proportion of the isotopes' abundance on earth. It is this weighting together that results in the numbers being fractional.
What would cause the average atomic mass to be close to a whole number?
The average atomic mass of an element is close to a whole number when the element has nearly equal amounts of its isotopes, with atomic masses that are close to whole numbers themselves. This occurs in elements with only one stable isotope or with stable isotopes that have similar abundances.
What are the radioactive isotopes?
radioactive isotopes are isotopes with irregular nuclear composition, it emits energy due to decay of atomic nucleus.
What is the weighed average mass of an atom of an element?
The weighted average mass of an atom of an element is determined by considering the mass of each isotope and its relative abundance. This mass is often found on the periodic table as the atomic mass or atomic weight, which takes into account the masses and abundances of all naturally occurring isotopes of that element.
What radiation does atomic bomb release?
An atomic bomb primarily releases ionizing radiation in the form of gamma rays, neutrons, and beta particles. Gamma rays are highly penetrating and can cause significant damage to biological tissues. Neutrons, emitted during the fission reaction, can also interact with matter, leading to further radiation exposure. Additionally, the explosion produces radioactive fallout, which can contaminate the environment with various isotopes.
What caused the illness after the atomic bomb?
What causes illness for the people who were exposed to the Atomic bombs was that the radiation produced from the emitted alpha particles can burn the skins and then penetrate it to cause permanent mutation inside the cells. Depending on what individual cells) is damaged, it can cause diseases such as cancer, which can kill.
What two isotopes cause the nucleus to split an atom bomb?
The isotopes are uranium-235 or plutonium-239.
How are elements with atomic numbers higher than 92 created?
Isotopes were then explained as elements with the same number of protons, --- In the 1950s, the development of improved particle accelerators and --- All known isotopes of elements with atomic numbers greater than 82 are radioactive.Evaa_I_WILL_H3LP_YOU
