(a)
Interpretation:
The suitable elements should be identified for given electronic configuration.
Concept introduction:
The periodic table is given in figure 1,
Figure 1
The electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. Atom consists of s, p, d, and f orbitals.
The Aufbau principle:
The Aufbau principle is states that in the ground state of an atom, electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels. For example, the 1s shell is filled before the 2s subshell is occupied.
The subshell ordering by this rule is

- The elements oxygen and sulfur have similar chemical properties because they both have six electrons in their outermost electron shells. Indeed, both elements form molecules with two hydrogen atoms, water (H2O) and hydrogen sulfide (H2S). Surprisingly, at room temperature, water is a liquid, yet H2S is a gas, despite sulfur being much larger and heavier than oxygen. Explain why this might be the case.arrow_forwardHow many total atoms would be in one formula unit of (NH4)3PO4? 20, 4, 18, 16arrow_forwardCompound A has molecular formula C7H7X. Its 1H-NMR spectrum shows a singlet at 2.25 ppm and two doublets, one at 7.28 ppm and one at 7.39 ppm. The singlet has an integral of three and the doublets each have an integral of two. The mass spectrum of A shows a peak at m/z = 126 and another peak at m/z = 128; the relative height of the two peaks is 3:1 respectively. Identify what atom X is, explaining your reasoning and identify Compound A, explaining your reasoning.arrow_forward
- 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_forwardHow many oxygen atoms are in this molecular formula? 3H2 Oarrow_forwardOn the indicated blue bonds, which ones are able to rotate?arrow_forward

What is the identity of Z, and how many electrons does Z3+have?arrow_forwardPolonium 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_forward

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_forwardB. A chlorine atom (Cl) becomes a negatively charged chloride ion (Cl) when it gains an electron and fills the vacancy in its third, outermost shell.
