Did the existence of isotopes affect the validity of the atomic theory?
Dalton's theory said that "atoms of the same element are the same as each other in terms of mass, color, and size." We know that this cannot be true because isotopes of the same element, oxygen for example O-16 and O-17, have different mass numbers (atomic mass). Dalton's theory said that "atoms of the same element are the same as each other in terms of mass, color, and size." We know that this cannot be true because isotopes of the same element, oxygen for example O-16 and O-17, have different mass numbers (atomic mass).
Is the two atoms have same atomic radius?
Not necessarily. The atomic radius of an element is determined by the size of the atom's electron cloud. While atoms of the same element would typically have the same atomic radius, atoms of different elements can vary in size due to differences in their electron configurations and the number of protons in their nuclei.
Why do all isotopes of an element have the same chemical proporties?
Chemical reactions involve electrons - not protons or neutrons. All isotopes of the same element have an identical number of electrons (just the number of neutrons differs) and hence the chemical properties are identical/very similar.
How can one determine the atomic size of an element?
The atomic size of an element can be determined by measuring the distance between the nuclei of two bonded atoms of that element. This distance is known as the atomic radius and can be calculated using various experimental techniques such as X-ray crystallography or spectroscopy.
How do the atoms of elements 19 and 35 compare in size?
The atom of element 19 (potassium) is larger in size than the atom of element 35 (bromine) because atomic size generally increases as you move down a group in the periodic table. Potassium is in a lower period and has more electron shells than bromine, which contributes to its larger atomic size.

Why isotopes of the same element have the same chemical properties?
The chemical properties of an element are determined by the number and configuration of its electrons, which depends on the size of the charge of the atom's nucleus. The charge is determined by the number of protons. Isotopes of a given element differ only in the number of neutrons, which do not have a charge and thus do not affect the electron configuration.

How is the atomic mass determined?
Atomic Mass is the number of protons in an atom plus the number of neutrons in the same atom.

Chemical reactions involve electrons - not protons or neutrons. All isotopes of the same element have an identical number of electrons (just the number of neutrons differs) and hence the chemical properties are identical/very similar.
Is the atomic mass and atomic number the same number?
An Isotope of an element is an atom that has the same number of protons, (number of protons is the defining feature of an element) but different number of neutrons.Because The mass number is the sum of protons and neutrons, different isotopes have different mass numbers.

Which is the smallest element in the periodic table?
Hydrogen has the smallest atomic size of any element.

Which is the element having biggest atomic size?
May be Cesium(Cs)
