You have to solve problems that don’t have a clear solution
Answer:
check the explanation
Explanation:
In the periodic table, as you move from the left to the right, the atomic number will increase, so the number of electrons, protons and neutrons, that mean the atoms are going to have more electrons in the last energetic level. For example, all the elements of group 1 have 1 electron in the outside layer, the family 2 will have 2 electrons, and so.
The elements with 1,2 or 3 electrons in the outside layer can give their electrons easily to join to another atom, meanwhile the elements that have 5,6 or 7 electrons in the outer layer, tend to attract electrons when they join with another atom.
The isotopes are atoms of the same element but with different number of neutrons, and because of this difference can be used in biology to detect traces of minerals in the body because some isotopes can react with colorants to be analyze.
My answer is a. environmental science. This
deals with more with the study of the environment rather than health and
wellness. It consists of various
disciplines such as biology, minerology, soil science, geology, zoology and
other related fields. The other three
deal directly with health and wellness.
This could be either c or d because technically, sodium ions and chloride ions are the most abundant, not sodium and chlorine, and there is also a significant amount of calcium in seawater. The answer you're looking for is most likely d but check with your teacher to be sure! (it is not A or B as salt is not an element, but rather a type of compound)
