How are atoms of the same element the same?
Atoms of the same element always have the same number of protons, same Z, but often have different numbers of neutrons, therefore, different mass numbers.

What does it mean if atoms are in the same group?
In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts. This similarity in both the composition and structure of their atomic valence shells implies a corresponding similarity in both their chemical and physical properties.

Are all atoms of the same elements exactly the same?
No. Two atoms of the same chemical element are typically not identical. First of all, there is a range of possible states that the electrons of an atom can occupy. Two atoms of the same element can be different if their electrons are in different states.

Why are atoms of the same element the same?
Atoms of the same element have the same atomic number so the number of protons (and electrons) are same. But they have same or different mass numbers (like that for isotopes). Different mass number will have different number of neutrons. Was this answer helpful?

How are to atoms of the same element alike?
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 are atoms of the same element different?
The atoms of different isotopes are atoms of the same chemical element; they differ in the number of neutrons in the nucleus.

Which makes the atoms of an element identical?
Dalton’s Atomic Theory of Matter – Atoms of a given element are identical (meaning they have the same mass and properties). – Atoms retain their identity in all chemical reactions. � This is basically the Law of Conservation of matter stating that an equal amount of mass exists before and after a reaction.

What does it mean when atoms are in the same period?
A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.

Why are atoms in the same group?
Reason: Elements in a group have the same number of electrons in the outermost shell hence they have similar chemical properties. Q. Assertion :Elements belonging to the same group have similar chemical properties. Reason: Elements of a group have same number of valence electrons.
