(a)
Interpretation:
The elements that are located in period 3 of the periodic table have to be chosen from carbon, chlorine, phosphorus, calcium, copper and bromine.
Concept Introduction:
Periodic law states that if the elements are arranged in increasing order of
Location of an element in a periodic table can be given by the period number and the group number. The horizontal row in a periodic table where the elements are present is known as Period. The vertical column in a periodic table where the elements are present is known as Group.
(b)
Interpretation:
The elements that belong to halogen family have to be chosen from carbon, chlorine, phosphorus, calcium, copper and bromine.
(c)
Interpretation:
The elements that readily conduct heat have to be chosen from carbon, chlorine, phosphorus, calcium, copper and bromine.
(d)
Interpretation:
The elements that have its nuclear charge less than +16 has to be chosen from carbon, chlorine, phosphorus, calcium, copper and bromine.

- Polonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason that authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po become after it emits an alpha particle?arrow_forwardPolonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons.

- A principal shell with a value of n=3 would contain s,p,d, and f orbitals true or falsearrow_forwardWhat if there are a different number of Neutrons? Sometimes elements have a different number of neutrons than usual, so therefore have a different atomic mass. This is what we call an Isotope (a variant form of an element which has the same number of protons but a differing number of neutrons). Sometimes we’ll see Isotopes labeled with their new mass like this: 14C = this is Carbon 14. Notice it has a different mass than what is on your periodic table The average mass of all the isotopes is defined as an element’s Atomic Weight. Can you answer questions about these Isotopes?

- Many radioactive isotopes are used in medicine for imaging and treatment purposes. The specific isotopes used depends on the particular organ or body system being studied (for example, Xe-133 is used to image lung function and blood flow.) Technetium-99m is a common radioactive isotope using for a variety of medical applications. It is produced from the decay of Molybdenum-99 and has a half-life of 6.01 hours. What are some of the applications of Tc-99m? While harder to access, another radioactive isotope of technetium, Tc-93, has a half-life of 2.73 hours. If it were easier to harvest, would this be a good substitute for Tc-99m? (remember to explain why for full credit) While Tc-99m has a half-life of 6.01 hours, its decay product has a half-life of 213,000 years. While the medical community considers it to be reasonably safe, within the limits of testing, does this make sense considering both chemical and biological principles?
