Who is the scientist who recognized the periodic table for atomic number?
The scientist who recognized the periodic table for atomic number was Henry Moseley. He discovered that elements should be ordered by atomic number rather than atomic mass, which led to the modern understanding of the periodic table.
Why is the neutron's number N equal to the mass number A minus the atomic number Z?
The neutron number ( N ) is defined as the difference between the mass number ( A ) and the atomic number ( Z ) because the mass number represents the total number of protons and neutrons in an atomic nucleus, while the atomic number indicates the number of protons. Therefore, by subtracting the atomic number from the mass number, you obtain the number of neutrons in the nucleus, which is essential for understanding nuclear stability and the isotopic composition of elements. This relationship is fundamental in nuclear physics and chemistry.
What is Henry moseley atomic model?
Henry Moseley's atomic model, developed in the early 20th century, refined the understanding of the atomic structure by introducing the concept of atomic number as a fundamental property of elements, rather than atomic mass. He established that each element's identity is determined by the number of protons in its nucleus, leading to the modern periodic table's arrangement by atomic number. This work resolved inconsistencies in the periodic table and provided a more accurate basis for understanding chemical behavior. Moseley's contributions significantly advanced the field of atomic physics and chemistry.
Which number on the periodic table determines the number of electrons in the atoms of the elements?
The atomic number on the periodic table determines the number of electrons in the atoms of the elements. Each element has a unique atomic number, which corresponds to the number of protons in the nucleus and thus the number of electrons surrounding the nucleus in a neutral atom.
Who discovered atomic no?
The concept of atomic number was introduced by Henry Moseley in 1913 through his experiments on X-ray spectra of elements. Moseley's work led to the modern understanding that atomic number is the number of protons in an atom's nucleus, which determines an element's chemical properties.
Why is the atomic number on the periodic tabe never a whole number?
The question is based on a complete lack of understanding as to what the atomic number is! They are always, without exception, whole numbers.
What is the atomic number of a ozone molecule?
to my own understanding ozone does not have an atomic number
Who discovered atomic number?
The concept of atomic number was proposed by Henry Moseley, a British physicist, in 1913. Moseley's research on X-ray spectra of elements led to the reorganization of the periodic table based on atomic number. His work established the modern understanding of the organization of elements by their atomic numbers.

What did Henry Mosley determine that contributed to understanding the atom?
Henry Mosley determined the concept of atomic number, which is the number of protons in an atom's nucleus. This discovery helped organize elements on the periodic table in a more accurate and systematic way, leading to a better understanding of atomic structure and behavior.

What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
This element has the atomic number that is double the atomic number of silicon?
The element with an atomic number that is double the atomic number of silicon is germanium, with an atomic number of 32. Silicon has an atomic number of 14.
