no they are not ]
He concluded that all atoms of an element have same mass and identical chemical and physical properties.
Atoms with the same atomic number and same chemical properties in their purest form are isotopes. Isotopes have the same number of protons and electrons but different number of neutrons. This does not affect their chemical behavior but may affect physical properties like atomic mass.
No. Atoms of the same element have the same chemical properties.
Helium atoms have the same physical properties regardless of whether they are found on the Sun or on Earth. The properties of an element, such as its atomic number and mass, remain constant regardless of its location. However, the environment in which helium atoms exist can affect their behavior, such as temperature and pressure differences, which could influence their physical interactions.
nope
Atoms that have the same number of neutrons are isotopes. Isotopes have the same atomic number but different atomic mass. This is significant because isotopes of an element have similar chemical properties but may have different physical properties, making them useful in various scientific and practical applications.
These two atoms are isotopes of each other. They have the same atomic number (protons) but different mass numbers due to their different numbers of neutrons. This means they will differ in terms of stability and possibly some properties, but they will have the same charge and occupy the same position on the periodic table.
All atoms of one type were identical in mass and properties. (Apex 2021)
Isotopes of the same element have the same number of protons in their nucleus (atomic number), but a different number of neutrons. This means they have the same chemical properties but may have different physical properties due to their mass difference.
Isotopes are atoms with the same number of protons (atomic number) but different numbers of neutrons, resulting in different atomic masses. These isotopes have similar chemical properties but may have different physical properties due to their different masses.
They have same no. of electrons and protons so have same chemical properties however they have different no. of neutrons resulting in different atomic mass. eg- 23592U and 23992U
It is a matter of how they are arranged and electrically charged that changes the properties of them
