If you have a neutral atom (like you normally would) then the number of electrons is equal to the number of protons. If you had more electrons then the charge would be negative. In this case, you would have 20 electrons.

How do astronomers explain the formation of the milky way galaxy
nadezda [96]

Galaxy Formation.  One says that galaxies were born when vast clouds of gas and dust collapsed under their own gravitational pull, allowing stars to form. The other, which has gained strength in recent years, says the young universe contained many small "lumps" of matter, which clumped together to form galaxies.

How are matter and substances related?
Nitella [24]
Matter and substance are definitely related. All substances are matter but all matters are not substance. A matter can consist of numerous substances. Matter is generally a loose term used in respect to a substance. Any physical object can be casually called a matter. Matter and substance are sometimes used for the same context, but it is completely wrong. Numerous examples have already proved that a matter may or may not be a substance depending on its physical nature, but a substance is always a matter.
