Drop out my dude whatever this is ain’t worth it
Answer: it has one proton and electron
Explanation:
<span>In physics WAVELENGTH IS THE DISTANCE BETWEEN REPEATING UNITS OF A PROPAGATING WAVE of a given frequency. It is commonly designated by the Greek letter lambda (λ). Examples of wave-like phenomena are light, water waves, and sound waves. The wavelength is related to the frequency by the formula: wavelength = wave speed / frequency. Wavelength is therefore inversely proportional to frequency. Higher frequencies have shorter wavelengths. Lower frequencies have longer wavelengths, assuming the speed of the wave is the same.</span>
Answers and Explanations:
Physical properties are characteristics of substances that can be seen without a change in its chemical composition.
Here, physical properties are:
- density
- color
- luster
- taste
- abundance
- source
I'm not completely sure what you mean by "source", but I'm going to assume you mean the substance's origin found in nature.
The cyclo-heptatrienyl anion will be considered as antiaromatic compound.
A cyclic compound with a greater energy electron system due to the existence of a 4n delocalized electron is what makes up an anti-aromatic chemical.
Due to its eight pi electrons, the cycloheptatrienyl anion (also known as the tropylium anion) should be antiaromatic; yet, the extra lone pair on one carbon could enable that carbon to become 
hybridized, placing the extra electrons in an orbital. It would become non-planar as well as non-aromatic as a result.
Therefore, the cyclo-heptatrienyl anion will be considered as antiaromatic compound.
