Matter that emits no light at any wavelength is called DARK MATTER.
Answer: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion.
That's what scientists and other technical people call the object's "<em>volume</em>".
Answer:
"What is the best advice a parent can give a child?"
Explanation:
