They have the same number of protons in their nuclei.
all atoms of the same kind of matter have the same number of protons in them. 🙈
All atoms of the same kind of matter are similar because they have the same number of protons in their nucleus, giving them the same atomic number. This determines the element to which they belong and establishes their chemical properties. Additionally, atoms of the same element have identical electron configurations in their outermost energy levels.
All gold atoms (excepting artificial isotopes) are similar.
molecule
all of the same or similar kind or nature
The reason for similar properties among the elements is due to the resemblance in the electronic configuration of all the elements of a family. For example :- Each element of Alkali metals family has 1 electron in their outermost shell. Hence, they all have similar properties
A substance in which all atoms are identical is called an element.
Isotopes are atoms of the same element with varying number of neutrons. Thus, not all atoms are the same.
An atom is the smallest piece of an element. Said another way, and element is made up one and only one kind of atoms.
Yes: All atoms contain protons and electrons, and all except the atoms of hydrogen-1 also contain neutrons.
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
All atoms don't have the same number of Protons.
