(a)
Interpretation:
The radio isotope element should be identified which is used for the cancer treatment.
Concept Introduction:
Isotopes: Elements have same
(b)
Interpretation:
The greatest density of the element should be identified.
Concept Introduction:
Density:
The nuclear density can be calculated from the size of the nucleus. The nucleus density is based on the number of protons and neutrons.
(c)
Interpretation:
The element should be identified which is not found in nature.
Concept Introduction:
The first 92 elements occur naturally, Technetium (atomic number 43) and promethium (atomic number 61) were synthesized by chemist before identified in nature.

- 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. They can be stopped by, for example, a sheet of paper or a few inches of air. This property is one reason why 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 decay into after it emits an alpha particle?arrow_forwardAn isotope of sodium (Na) has a mass number of 22. How many neutrons does it have? a. 11 b. 12 c. 22 d. 44arrow_forwardVisit this website (http://openstaxcollege.org/l/ptable) to view the periodic table. In the periodic table of the elements, elements in a single column have the same number of electrons that can participate in a chemical reaction. These electrons are known as valence electrons. For example, the elements in the first column all have a single valence electron—an electron that can be donated in a chemical reaction with another atom.

- The triple point of an element is at 75 torr and 125°C. This means that liquid is more dense than solid cannot exist at 1 atmosphere pressure cannot have a vapor pressure less than 75 torr cannot exist above 125 degrees Celsius What is the electron geometry (or electron arrangement) around an atom in a molecule or ion which is surrounded by three lone pairs of electrons and two single bonds T-shaped see-saw trigonal planar trigonal bipyramidal linear A red blood cell placed in pure water will swell because water moves from a higer osmotic pressure to a lower osmotic pressure the osmotic pressure is greater in the cell than in the water the osmotic pressure is the same in the cell and the water the somotic pressure is greater in the water than in the cellarrow_forwardElemental analysis of a compound with molar mass 342.3 g/mol gives the following mass percent composition: C 42.11%, H 6.48%, O 51.41%.
