How were the positions of isotopes resolved in modern periodic table?
The positions of isotopes in the modern periodic table are not explicitly shown; instead, elements are represented as whole entities, with isotopes being variations of these elements based on their neutron count. The periodic table is organized by atomic number, which corresponds to the number of protons in an element's nucleus. Isotopes of an element share the same atomic number but have different atomic masses due to varying numbers of neutrons. The average atomic mass listed on the table reflects the weighted average of all naturally occurring isotopes of an element.
Why does beryllium have an atomic mass of 9 instead of 8?
The atomic mass of an element is determined by the sum of the protons and neutrons in its nucleus. Beryllium has 4 protons and typically 5 neutrons, resulting in a total of 9 nucleons (protons + neutrons). This is why its atomic mass is 9 instead of 8.
How are neutrons in an atom calculated?
As an example, take Americium 241 - 241 is the atomic weight. It is Atomic number 95 in the periodic table and so there are 95 protons. There are thus 241 -95 = 146 neutrons. That principle applies to all the elements.
What is C8 gas?
C8 is most likely referring to Carbon 8, which is an isotope of carbon with 8 neutrons instead of 6.
Why are elements atomic mass not in strict increasing order in the periodic table?
Elements in the periodic table are arrange by atomic number (number of protons) because various isotopes of elements exist with different atomic masses (atomic mass being determined by the number of neutrons added to the number of protons). The chemical properties are mainly dependent on the electrons, or in some cases the charge of the protons, which is independent of the number of neutrons.
How are isotopes placed in the periodic table?
Isotopes and their prevalence are not shown on the periodic table. Instead, the atomic weight shown for each element is an average of the atomic weights of all naturally-occurring isotopes (calculated from percentages occurring on Earth).

How would the modern periodic table would be different if elements were arranged by average atomic mass instead of by atomic number?
how would the modern Periodic Table be different if elements were arranged by average Atomic Mass instead of by atomic number
What do electron microscopes use instead of light to magnify?
it is the neutrons
What is one problem that chemists in about 1800 had to solve before the periodic table?
What to use instead of the periodic table.
Neutrons in potassium?
I'm not sure... but as soon as I figure out the answer I will post the answer... sorry. This answer is better than the one the person before me posted... They said poop and I thought that that was not a true answer for sure and it's nothing to play about and to put a fake answer on here :)
What elements does contain 35 number of neutrons and 14 protons?
A silicon isotope called silicon 35, with 35 neutrons instead of the regular 14.
Why you use slow neutrons instead of fast neutrons in nuclear reaction?
in reacter U-235 fission is due to slow neutrons because in reacter the probability of fission from fast neutron is approximatly zero.
Why does beryllium have an atomic mass of 9 instead of 8?
The atomic mass of an element is determined by the sum of the protons and neutrons in its nucleus. Beryllium has 4 protons and typically 5 neutrons, resulting in a total of 9 nucleons (protons + neutrons). This is why its atomic mass is 9 instead of 8.

When neutrons were discovered were these neutrons created in the experiments?
Neutrons were discovered through experiments involving bombarding beryllium with alpha particles. Neutrons were not created in these experiments, but were instead found as subatomic particles that make up the nucleus of atoms.
What contribution did Mosley makers the development of the periodic table?
Henry Moseley showed elements in the periodic table should be in order by their atomic number instead of atomic mass.
