An atom with six electrons in its valence shell will have two unpaired electrons. The four electrons will occupy two orbitals fully, while the remaining two electrons will each occupy one orbital in accordance with Hund's Rule.
An atom with six electrons in its valence shell typically belongs to group 16 on the periodic table. In this group, Oxygen is a perfect example having 'six valence' electrons but only 'two of them are unpaired'. The four electrons are arranging themselves in two fully occupied orbitals, while the remaining two electrons each occupy one orbital, following Hund's Rule, which states that orbitals in the same subshell fill with one electron first, with spins parallel, before they begin to pair up. Therefore, an atom with six electrons in its valence shell would have two unpaired electrons.

Answer: 2
Explanation:
In order to have a complete shell, you need 8 total electrons.
The empirical formula of the compound containing 79.8% carbon and 20.2% hydrogen is CH₃
Divide by their molar mass
C = 79.8 / 12 = 6.65
H = 20.2 / 1 = 20.2
Divide by the smallest
C = 6.65 / 6.65 = 1
H = 20.2 / 6.65 = 3
Thus, the empirical formula of the compound is CH₃

Answer:
Carbon-dating techniques rely heavily on Chemistry
Explanation:
Carbon dating or the chemistry of carbon-dating involves the comparison of naturally occurring isotopes of carbon having the same number of proton with different numbers of neutron in their nucleus involving beta (β) radiation.

You can wrap your sandwich in Tin, an element from the periodic table.
The periodic table is a chart that organizes all known elements based on their atomic number, symbol, and atomic mass. To wrap a sandwich, you can use the element Tin, which has the atomic symbol Sn and atomic number 50. Tin is a soft, malleable metal that is often used as a coating for other metals to prevent corrosion. It can be melted and shaped into thin sheets, making it suitable for wrapping a sandwich.

The pun answer to the question 'what do you wrap your sandwich in?' is 'Aluminum', because aluminum is an element from the periodic table and aluminum foil is often used to wrap sandwiches.
The pun in this question refers to an element from the periodic table to humorously answer the question "What do you wrap your sandwich in?". One possible response could be: "You wrap your sandwich in Aluminum", since the word "wrap" is commonly associated with aluminum foil, which is used to wrap and protect food, like a sandwich. Aluminium is a chemical element in the periodic table with the symbol Al and atomic number 13. It's a silvery-white, soft, non-magnetic and ductile metal, which makes it ideal for creating thin, flexible sheets like aluminum foil for food wrap.
