As scientists work hard for the results, they may get biased and may sometimes come up with an answer that is based on that. In order to avoid such circumstances, scientific method is put into practice.
Explanation:
- Personal preferences can some times affect a scientific answer. That is not desirable as the experiments will be repeated by different individuals and the same results should be obtained.
- That leads to the importance of documentation of systemic observation, formation of hypothesis and the experimentation to confirm the results, which is the scientific way of coming up with the answer to a scientific problem.
- Scientific methods thus helps in bringing more credibility to findings of the scientists and can be repeated by others to obtain the same results.

This means that neutral zinc atom has a total of 30 electrons surrounding its nucleus. To see how many of these electrons are valence electrons, write the electron configuration of a neutral zinc atom. Notice that the outermost shell, which for zinc is the fourth shell, n=4, has two electrons. Hope this helps. :)
