Answer: How do contrasting colors affect the quality of a painting?
Explanation:
The object study of science is objective phenomena, which are those phenomena that can be measured in a form that every ones agree because they do not depend on the particular subject that is involved in the study.
Color of light, mating behaviors of bees, soil pH, the productivity of fruit trees, temperature, and the amount of oxygen able to dissolve in water are variables or characteristics that can be objectively measured, so they can be perfectly object of study of and answered by science.
On the other hand, the ability to contrast color and the quality of paintings are characteristic that are subjective: they depend on the subject that assess such properties. This makes that a question like "How do contrasting colors affect the quality of a painting?" cannot be answered by science.
Answer : The number of electrons in an atom is, 2 electrons
Explanation :
As we know that there are four quantum numbers which are principle quantum number, azimuthal quantum number, magnetic quantum number and spin magnetic quantum number.
The Principle quantum number, n = 3. That means the electron present in the third energy level.
The Azimuthal quantum number, l = 2. That means the electron present in the d sub-shell.
The magnetic quantum number, . That means it shows the 2 electrons present in one of the five 3d orbitals.
Hence, the number of electrons in an atom is, 2 electrons
<span>Carbon (C) is most likely to form covalent bonds with Beryllium (Be) or Sodium (Na) because they are both metals and covalent bonds are metals that share their valence electrons with the gases / non-metals to get to the stable octet. Krypton is a gas and Selenium is a metalloid</span>
