As you go across the period, the nuclear charge (or number of protons increase) but the shielding (or the number of shells) stays the same as all of the elements are on the same period. This causes the nu...
Once the sample is vaporised, high energy electrons are fired at the sample which knocks off a loosely held electron. (1) This step is known as election impact ionisation. (2) Due to the presence of a cha...
First, look at each of the groups connected to the two carbon atoms in the double bond. Rank these groups by priority based on the atomic mass of the atom connected to the alkene carbon. If both of the he...
Electronegativity is the measure of how strongly an atom attracts a bonding pair of electrons to itself. As group 7 is descended, the electronegativity decreases. This is because the size of the halogen a...
With these sort of questions, it's important to firstly think about what type of bonds make up the structure of the element. For this example, they both have metallic bonds which hold the structures toget...
