SHOE PRINT
Visit this link and look at the first to view a correctly scaled image of the
shoe print from the scene Determine the length of the shoe print in
appropriate significant digits and with correct units Type your answer
here 27.4cm
2. Use your measurement and the next to pages of the linked document
to determine the shoe size of the print. Type your answer here
COFFEE THERMOS
Your teacher filled up the thermos to the top with liquid, then
transferred that liquid to the graduated cylinder. Visit the same link from
the Shoe Print evidence, and scroll to page 4 Use images to
determine the volume of coffee that the thermos can hold in
appropriate significant digits and with correct units Type your answer

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
