Answer:
Is a substance that can maintain certain range of pH
Explanation:
A buffer is mixture of two salts that are complementary, one salt is acid and another is basic, but since then share some part of their structure, if you add to this mixture another acid, the basic salt can absorb it and still maintaining the same pH. If you pour a base, the acid salt will absorb it and again the final pH will remain the same. So the buffers are used to maintain the same pH does not matter if you add small quantities of an acid or base.
Answer:

A neutral atom has the same number of protons and electrons because in order for it to be a neutral atom the charges must be the same.
a neutron has no charge therefore it can be different then the number of protons and electrons in a neutral atom as it won't affect the charge.
