The Periodic Table give the atomic numbers and the atomic weights of chemical elements.
What else can I help you with?
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).
Why are isotopes not found on different sections of the periodic table?
Isotopes are not found on different sections of the periodic table because isotopes have the same number of protons and electrons as the element they correspond to, so they are placed in the same position on the table based on their atomic number. The different isotopes of an element have a different number of neutrons, which affects their atomic mass but not their position on the periodic table.
How will the modern periodic table be disturbed if isotopes of an element are discovered now?
The periodic table would be disturbed only if isotopes of a new element are discovered, because a periodic table is based on order of atomic number, not atomic mass. If new isotopes of a previously known element were discovered, the atomic mass shown in the periodic table might be changed, but this is very unlikely because the atomic masses shown in a periodic table are based on the naturally occurring distribution of isotopes, and any newly discovered isotopes would probably occur only in very small fractions of the total.
Where are the isotopes of the same elements having different atomic masses placed in the periodic table?
Isotopes of the same element with different atomic masses are placed in the same position on the periodic table because they have the same number of protons and electrons. The atomic number, which determines an element's position on the periodic table, is the same for all isotopes of an element.
How can the atomic mass of the element be lower than the element that came before it?
Because the periodic table is organized by atomic number, not by atomic mass. The general trend in the periodic table is a higher atomic mass as you go up atomic number, but there are exceptions.
What is the position of isotopes in the modern periodic table?
Isotopes are not specifically located in the modern periodic table because they have the same number of protons (same element) but different numbers of neutrons. However, isotopes of an element share similar chemical properties due to their identical electronic configurations.
By using the periodic table how did you determine how many neutrons are the most common isotope of an element?
Usually the periodic table would not be a good source to determine the number of neutrons; the periodic table focuses on the atomic number, which is the number of protons. An element with a given number of protons can have multiple isotopes, which are elements with the same number of protons but a different number of neutrons; in some cases there are a rather large variety of isotopes. Having said that, some periodic tables do represent the commonest isotope or commonest naturally occurring one but are still unlikely to list all possible isotopes.
What is a similarity and a difference between isotopes of an element?
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
Isotopes of a particular element in the periodic table have which nuclear property in common?
They have the same number of protons and electrons, but they (only) differ in the number of neutrons (and so they differ in atomic massaccordingly)
Which is more the number of elements or the number of isotopes?
The number of elements is more than the number of isotopes. There are 118 known elements on the periodic table, while each element can have multiple isotopes with varying numbers of neutrons. The number of isotopes per element can range from a few to dozens, depending on the element.
What structural element do all isotopes of an element have in common?
All isotopes of an element have the same number of protons in their nucleus. This is what defines them as being the same chemical element. The number of protons determines the element's atomic number.
what number on the element box has a decimal?
The number on the element box that has a decimal is the atomic mass of the element. This value represents the average mass of an element's isotopes, weighted by their natural abundance. It is typically found below the element's symbol in the periodic table and is usually not a whole number due to the presence of isotopes.
