Because in difrent materials atoms are more compact or less compact.if they are less compact then it will be easear for them to move
The molar mass is the mass of all atoms in a molecule we first obtain the atomic weights from the individual elements in a periodic table then count the number of atoms and multiply it by the individual atomic masses
Answer: An atom that has gained an electron.
Explanation:
The number of protons in an atom cannot change except for some exceptional circumstances.
Cations (or metal ions) are formed when atoms lose electrons, as they want to form a complete outer electron shell to become as stable as possible.
For example, potassium is a 1+ ion, because it has one electron in its outer shell (and in group one). Therefore, to become more stable that electron is lost to become an ion or cation. As one electron is lost, the potassium cation charge is 1+ as the charge of an electron is 1-.
