The knowledge of periodic table would be important in these three different careers such as medicine, pharmacology and engineering.
<h3>What is the importance of periodic table in following careers?</h3>
Periodic table is organised the whole elements vertically in groups and horizontally in periods with increasing atomic number.
The knowledge of arrangement of these elements serves alot of purposes in the following three different careers:
- Medicine: The element, iron is an important metal in the periodic table used in treatment of low blood levels.
- Pharmacology: The transition metals are useful in the field of pharmacology for the production of drugs. Example of such elements are chromium, manganese, cobalt, nickel, copper, and molybdenum.
- Engineering: The information of elements in the periodic table helps engineers in designing of materials used for constructions.
Therefore, the knowledge of periodic table is very important in these three different careers such as medicine, pharmacology and engineering.

Answer:
wave
Explanation:
'Wave' is a common term for a number of different ways in which energy is transferred: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields.
i hope this helps and your welcom
We can predict formula of ionic compounds by:
- Take a look at where the elements are listed on the periodic table.
- The amount of electrons that an element would need to gain or lose in order to resemble an atom of a nearby noble gas is one of the similarities that atoms in the same column as one another (group) tend to display.
- Alkali metal group I ions have +1 charges.
- Alkaline earth metals (group 2 ions) have a +2 charge.
- Nonmetal group 6 ions have a charge of -2.
- Halides in group 7 have a -1 charge.
- The charges of the transition metals cannot be predicted in a straightforward manner.
- Check out a table of charges (valences) to see potential values. The +1, +2, and +3 charges are most frequently employed in beginning and general chemistry courses.
- Keep in mind that the positive ion is always stated first when writing an ionic compound's formula.
These are the few guidelines we can use to product formula.
