For part 1, just copy them off of the periodic table. For example, element 1 is Hydrogen, and its symbol is H
Elements on the left usually lose electrons and elements on the right tend to gain them. Noble gases have no charge.
Answer:
thermal radiation
Explanation:
Outgoing Long-wave Radiation (OLR) is electromagnetic radiation of wavelengths from 3–100 μm emitted from Earth and its atmosphere out to space in the form of thermal radiation. It is also referred to as up-welling long-wave radiation and terrestrial long-wave flux, among others.
Answer: A) Ar
Explanation: Argon [Ar] has an atomic no of 18 and the electronic configuration is:
Ar :![1s^22s^22p^63s^23p^6](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E63s%5E23p%5E6)
Chlorine [Cl] has atomic no of 17 and thus the electronic configuration is :
Cl :![1s^22s^22p^63s^23p^5](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E63s%5E23p%5E5)
Magnesium [Mg] has atomic no of 12 and thus the electronic configuration is :
Mg :![1s^22s^22p^63s^2](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E63s%5E2)
Sodium has atomic no of 11 and thus the electronic configuration is :
Cl :![1s^22s^22p^63s^1](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E63s%5E1)
As we move across a period the number of electrons are being added to the same shell but the number of protons increases, thus the electrons are being tightly held and thus the atomic radius keeps on decreasing.
Thus the smallest atom would have a tightly bound electron nearer to the nucleus. As argon is the last element of the period, it is the smallest in the period and thus largest amount of energy will be required to remove the outermost electron.
A homologous series may be defined as a family of organic compounds having the same functional group, and the successive(adjacent) members of which differ by a CH

unit or 14 mass units.
Two consecutive members of homologous series of Aldehydes: CH

CHO and C

CHO
A carbon compound is made up of two parts: R−F, where R is the hydrocarbon part and F is the functional group part.
So, this R (hydrocarbon) part determines the physical properties of a compound and the F (functional group) part determines the chemical properties of the compounds.
Answer:
Root mean squared velocity is different.
Explanation:
Hello!
In this case, since we have a mixture of oxygen and nitrogen at STP, which is defined as a condition whereas T = 298 K and P = 1 atm, we can infer that these gases have the same temperature, pressure, volume and moles but a different root mean squared velocity according to the following formula:
![v_{rms}=\sqrt{\frac{3RT}{MM} }](https://tex.z-dn.net/?f=v_%7Brms%7D%3D%5Csqrt%7B%5Cfrac%7B3RT%7D%7BMM%7D%20%7D)
Since they both have a different molar mass (MM), nitrogen (28.02 g/mol) and oxygen (32.02 g/mol), thus we infer that nitrogen would have a higher root mean squared velocity as its molar mass is less than that of oxygen.
Best regards!
