Answer:
b)
Explanation:
the data for the average height of the plants in all three trails contains error
Might be D bc it’s the only one that makes sense to me
The answer is; D
Diffraction of light occurs when the light encounters an obstruction that is smaller than its wavelength. The water droplets in the clouds can be very small and be closer in size to the wavelength of light. When sunlight encounters a cloud droplet, light waves are altered and interact with one another in a similar manner as the water waves causing fringes of light around clouds.
One valence electron is lost by Lithium
<h3>What is Electron ?</h3>
Unattached or attached to an atom, an electron is a negatively charged subatomic particle. One of the three main types of particles within an atom is an electron that is bound to it. The other two are protons and neutrons.
- Due to the fact that full valence shells are more stable states and that all noble gases have them, lithium wants to lose electrons in order to become like helium. Consequently, alkali metals lose one electron to achieve the closest noble gas configuration.
- Each lithium atom loses an electron to become a Li+ cation when it forms chemical compounds with other elements. The anions in ionic compounds that are negatively charged are therefore attracted to these. There are many applications for lithium compounds.
- Since full valence shells are more stable states, and all noble gases have them, lithium wants to lose electrons to become like helium. In order to obtain the nearest noble gas configuration, alkali metals must lose one electron.

The
mass of an atom comes from the protons and neutrons that are found in the
nucleus. The number of protons is the atomic number of an element. To find the
number of neutrons, subtract the atomic number from the mass of an atom. The number of atoms of an
individual element be determined by using a chemical formula and adding all of
the subscripts together after the reaction is complete. The key in the balancing of chemical reaction is to make sure that you got the
exact chemical formula of the substance that is reacting and the yielded
product. After getting the formula, identify first the hardest element/atom to
be balanced such as Na, Zn, Cl, C, O, etc. Then proceed to the easier ones such
as O, H. Make sure to note the atoms present in the molecule of the substance.
