Do atoms of different elements have different properties?
Atoms of different elements have different chemical properties. (These differences may range from very slight, such as those between the noble gases neon and argon, to vastly different, such as those between highly metallic sodium and strongly nonmetallic chlorine.)
What do atoms of two different elements must have different?
Atoms of different elements must have different atomic number. The atomic number of each element is different than other Elements.
Are atoms of an element similar?
No. Two atoms of the same chemical element are typically not identical. Since the states of the electrons in an atom are what determine the nature of the chemical bonding that the atom experiences, two atoms of the same element can react differently if they are in different states.
Who said atoms of different elements are different?
Scientist who contributed to the modern atomic theory.

How are atoms of the same element similar and different?
ISOTOPES AND ATOMIC MASSES For many of the chemical elements there are several known isotopes. Isotopes are atoms with different atomic masses which have the same atomic number. The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.
How are atoms of different elements similar and different?
This means that all atoms of the same element have the same number of protons. What makes atoms of various elements different from each other is their number of protons. In other words, each element is composed of atoms that have a specific number of protons.
Are all atoms of the same element exactly the same?
Who came up with atoms of the same element are exactly alike?
Dalton
Dalton proposed that every single atom of an element, such as gold, is the same as every other atom of that element. He also noted that the atoms of one element differ from the atoms of all other elements.
Why atoms of the same element are the same?
Atoms of the same element consist of the same atomic number that is number of protons or electrons and different mass number that is number of neutrons. This variation or change in the number of neutrons in an atom gives rise to different isotopes of an element. An element with different isotopes occurs in nature.
How different atoms of the same element could have different atomic mass?
Atoms of the same element have the same number of protons, but different isotopes have different numbers of neutrons. Different isotopes of the same element have different masses because they have a different number of neutrons.
How are atoms both similar and different?
The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element. We refer to the atoms of the same element with different numbers of neutrons as “isotopes”.
