Molecule: two or more different or same atoms chemically bonded together. A mixture contains two or more substances, that are not chemically bonded together. A compound is a pure substance, while a mixture is not.
The answer is B. They all have backbones. They can all do many tasks and their backbone allows them to do so. All mammals have backbones. Although an alligator is a reptile it still has a backbone
Answer:
The ion's sizes and their radius ratio.
Explanation:
Ionic compounds take the form of three dimentional arrays by alternating anions and cations in order to minimize the potential energy of the system by maximizing the attractive force between opposite charges.
<em>The resultant geometric structures are known as crystal lattices and their arrangements depend on the ion's sizes and, since they are bound though electrostatic attraction, their radius ratio.</em>

Answer:
The answer to your question is below
Explanation:
Atomic mass = 65.39 g
Searching this number in the periodic table we find that the element is Zinc.
Then:
# of Protons = 30
# of neutrons = atomic mass - # of protons
= 65.39 - 30
= 35.39
# of electrons = # of protons = 30
We have to get the formula of methionine.
The formula of methionine is
Methionine is an essential amino acid of human. It is white crystalline solid.
The formula of methionine is C₅H₁₁NO₂S. Methionine contains five carbon atoms, eleven hydrogen atoms, one nitrogen atom, two oxygen atoms and one sulphur atom.
It contains one amino group (-NH₂) and one carboxylic acid group (-COOH). Atoms are depicted in C-atom in grey, H-atom in ivory, O-atom in red, N-atom in blue and S-atom in yellow.
