Answer:
3 molecules
Explanation: i got it right on the test, also because the 2 other ones are compounds because they have hyrdogen and oxygen attached and molecules just have particles of one element attached
Answer: There are 4.09×1024 atoms of phosphorus in 3.40 mol copper(II) phosphate.
Amino acids are categorized by their chemical properties on the basis of the sequence of side chain (R group).
<h3>What are amino acids?</h3>
Amino acids are known as the 'building blocks of the life' as they help in the formation of proteins inside the body.
Side chain of amino acids is specific in nature and are known by the name of R group, these R groups are attached with the alpha carbon atom. R groups characterizes below properties of the molecule:
- Shape
- Size
- Charge and
- Reactivity
Hence R group describes the chemical properties of amino acids.

Answer:
4) transferred from the valence shell of one atom to the valence shell of another atom
Explanation:
Electrons are located outside of the nucleus which contains the protons and the neutrons.
For bonds to form, valence electrons located in the outermost shell electrons are involved. These are the valence electrons. These outer shell electrons can be shared or transferred between two combining atoms to form stable atoms.
In ionic bonds, the electrons are transferred from one specie to another. The atom that loses the electrons becomes positively charged and the receiving atom becomes negatively charged. This is the crux of ionic bonds.
