Multiply the volume and density together. Multiply your two numbers together, and you'll know the mass of your object. Keep track of the units as you do this, and you'll see that you end up with units of mass (kilograms or grams). Example: We have a diamond with volume 5,000 cm3 and density 3.52 g/cm3
ion, proton
Explanation:
Ions and protons have profound relationships.
An ion is an atom that has lost or gained electrons.
A proton is a positively charged subatomic particle.
What is the relationship between an ion and a proton?
- In an atom, there are three fundamental particles.
- Protons are the positively charged particles located in the nucleus of atoms.
- Electrons are the negatively charged particles orbiting round an atom.
- Neutrons have no charges and they occupy the nucleus with protons.
Atoms are electrically neutral and this implies that they have equal number of protons and electrons.
In an ion, the number of protons and electrons differ.
For positive charged ions, the number of protons is more suggesting they have lost electrons.
For negatively charged ions. the number of protons is less suggesting they must have added electrons.
Compound are combinations of different atoms.
