Nb, the transition metal(d) subshell will always be n-1, meaning the 3d subshell will be in row(period) 4. So if it’s 4d then it is row(period) 5, and if it has 3 valence electrons then the element is located in column V, or the third column in the transition metal section.
Answer: 
, 
Explanation:
Temperature of the gas is defined as the degree of hotness or coldness of a body. It is expressed in units like 
and 
These units of temperature are inter convertible.
We are given:
Temperature of the gas = 
Converting this unit of temperature into by using conversion factor:
Converting this unit of temperature into by using conversion factor:
Thus the temperature on the Celsius and Kelvin scales are and respectively.
Protons are not the only subatomic particle that has a charge, electrons do to and they are negatively charged. Neutrons are situated in the nucleus of the atom, which means that they do not orbit it. Subatomic particles have different masses.
You are then left with Electrons are the subatomic particles with the smallest mass as your answer.
Yes
Methane also is the chief constituent of natural gas, which contains from 50 to 90 percent methane (depending on the source), and occurs as a component of firedamp (flammable gas) along coal seams.
Formaldehyde is an organic compound.
