What of these subatomic particles are represented by atomic number?
Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.
Why did Mendeleev not consider the number of subatomic particles as a way to organize the elements?
The concept of atomic number had not yet been developed at the time of the first periodic tables, when atoms were still considered "indivisible units" and the concepts of protons, electrons, and neutrons were not yet known.
What is the total number of subatomic particles in the nucleus of an atom bi?
In this case, the number 209 represents the sum of protons + neutrons.
How do you find the atomic numbersof an subatomic particles?
The atomic number of a subatomic particle is determined by the number of protons it has. Protons have a positive charge and are located in the nucleus of an atom. The number of protons in an atom's nucleus is equivalent to its atomic number.
As you move across the periodic table for left to right each element gains one proton and one?
Electron. In a stable element the number of protons (+ charged subatomic particles) must match the number of electrons (- charged subatomic particles) and neutrons (neutral or uncharged subatomic particles). At least that's how I remember it from my school days.
What of these subatomic particles are represented by atomic number?
Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.
What is the subatomic particles on which the atomic number is based?
Number of protons in the nucleus is the atomic number.
What is the subatomic particle and the calculation derived from it that is not found in the periodic table?
Subatomic particles are protons, neutrons and electrons; the number of protons and electrons (in the neutral state) are equal to the atomic number of an element.
Which subatomic particle corresponds to the atomic number or the periodic table?
the number of protons
What 2 subatomic particles can you determine from the atomic number?
Atomic number is same as the number of protons and number of electrons.
Where are the nuetrons found on the periodic table?
Neutrons are sub-atomic particles. The Periodic Table is an arrangement of the elements (atoms) made from these subatomic particles. Thus Neutrons by themselves have no place in the Periodic Table. However as all elements/atoms (except Hydrogen) contain some Neutrons, it is possible to find out how many using the information presented on the Periodic Table. The number of Neutrons present in an element/atom can be determined by subtracting the atomic number of an element/atom from its atomic mass.
Name the subatomic particles that the number of this particle is always the same as the atomic number?
The proton
The atomic number for an element is the total number of subatomic particles?
False; the atomic number is the total number if protons in the nucleus only.
What is the number of subatomic particles of protons?
The number of protons is equal to the atomic number of a chemical element.
What is ment by atomic number?
Atomic Number is the amount of Protons (positively charged subatomic particles) contained in the nucleus of an atom.
What 2 subatomic particles can you determine form the atomic number?
The number of protons as well as the number of electrons.
Why did Mendeleev not consider the number of subatomic particles as a way to organize the elements?
The concept of atomic number had not yet been developed at the time of the first periodic tables, when atoms were still considered "indivisible units" and the concepts of protons, electrons, and neutrons were not yet known.
