In a covalent bond, the atoms bond by sharing electrons. Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
Fungus: Important because it breaks up several dead leaves, particles, etc, and puts nutrients back in the ground.
Carnivores: eat dead animals, no stinky rotten meat around.
Answer:
Dependent variable: If calcium is given, then bone strength will increase.
Explanation:
Answer:
As metals are giant lattice structures, the number of electrostatic forces to be broken is extremely large, and so metals have high melting and boiling points. This means that the melting point and boiling point of metals are more similar to those for ionic compounds than for covalent substances.
