no different elements are combined chemically to make different brands .
A pure substance in which all the atoms have the same atomic number or number of protons is an element.
A pure substance is a material made of only one type of particle, such as atoms or molecules, and all the atoms in a pure substance have the same atomic number or number of protons. This means that all the atoms in a pure substance are of the same element.
Pure matter substances can be elements, compounds, or mixtures where all components are the same throughout. Examples include pure water (H2O), pure iron (Fe), and pure table salt (NaCl).
Pure substances have identical particles. This means that all samples of a pure substance will have the same type and arrangement of particles, whether they are atoms, molecules, or ions. Examples of pure substances include elements and compounds.
Diatomic elements like hydrogen (H2) and oxygen (O2) contain pure covalent bonds because they consist of two atoms of the same element sharing electrons equally to achieve a stable electron configuration. In pure covalent bonds, the electronegativity of the atoms is similar, resulting in equal sharing of electrons between the atoms.
No, they are all different
a element is a pure substance
They all have to be the same size. They can be different brands but even then make sure the tires on the front axle are the same brand an the tires on the rear axle are the same brand. Do not mix brands on the same axle.
no there all the same due to the comity
no.
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
No.
An element.
There is no best, all pure essence is the same from every mine.
Yes
yes
no not all brands of diapers absorb the same amount of liquid
