What is the place of an element in the modern periodic table determined by?
The number of protons in an atom of the element.
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.
What does ir mean in the periodic table?
Ir refers to iridium element that is placed in group-9 and period-6 in the modern periodic table.
The first element on the periodic table is what?
Dimitri Mendeleev is credited with the the creation of the first modern and rational periodic table of chemical elements; but other chemists also had contributions.
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.
What is the place of an element in the modern periodic table determined by?
The number of protons in an atom of the element.
Are all the elements in the modern periodic table?
Any Element found by mankind is on the Periodic Table.
What Moseley determine in element?
Moseley determined that the number of protons in the nucleus of an atom corresponds to the element's atomic number. This discovery led to the modern periodic table where elements are arranged in increasing atomic number.
Which element in the 4th period obey the modern periodic law?
All of them do.

What characteristics of the element is used to organize the modern periodic table?
Atomic weight
Who is the father of the modern periodic table in element?
This is the Russian chemist Dimitri Mendeleev.
What is an unreactive gas that sinks in the air?
Argon.
What period is argon in?
Argon is in the third period of the modern periodic table.
What does ir mean in the periodic table?
Ir refers to iridium element that is placed in group-9 and period-6 in the modern periodic table.
Why is the position of hydrogen in the modern periodic table on the left side?
because its the element that created the earth
The group number on the periodic table corresponds to which characteristic of the elements of that group?
