All atoms of any single element have the same number of protons and electrons.
Not necessarily, because most elements have isotopes, which have slightly different weights. However, atoms of a particular element always have the same number of protons, equal to the atomic number of the element.
A pure element contains one sort of atoms, and all the elements have the same number of protons (which define the element). But the atoms can have different masses, so called "isotopes" (see link). Thus, chemically there is only one kind of atoms in a pure element, but there can be several physically different kinds of nuclei in a pure element.
Atoms, ions, and isotopes are all forms of the same element. They all have the same number of protons in their nucleus, which determines the element's identity.
No, atoms are the smallest units of matter that retain the properties of an element. The properties of an element are determined by the number of protons in its nucleus, which defines its atomic number and unique characteristics. When atoms combine to form molecules, the properties may change due to new interactions.
When all atoms in a substance are alike, the substance is an element. Each element is composed of atoms that have the same number of protons in their nucleus.
All atoms of a single element have the same number of protons in their nuclei, which defines the element's atomic number. This characteristic gives each element its unique chemical properties. Additionally, while they may vary in the number of neutrons (resulting in different isotopes), the electron configuration, which determines how atoms interact with each other, is also consistent among atoms of the same element.
No, the isotopes of a single element differ in the no. of neutrons
The commonalities that elements, compounds, and mixtures all have in common is that they all contain atoms. Even though they all contain atoms, the number of atoms vary in each of them.
He concluded that all atoms of an element have same mass and identical chemical and physical properties.
No, the isotopes of a single element differ in the no. of neutrons
Atoms, ions, and isotopes of an element all have the same number of protons in their nucleus, which determines the element's identity.
According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.
Not necessarily, because most elements have isotopes, which have slightly different weights. However, atoms of a particular element always have the same number of protons, equal to the atomic number of the element.
All the atoms have the same number of protons (element type).

The number of protons is identical in all atoms of an element.
