(a)
Interpretation:
Plutonium,
Concept introduction:
An atom is a single entity there is no bonding for an atom alone. A molecule is the combination of two or more atoms of same or different elements bonded together by a covalent bond. A formula unit is the combination of atom of two or more elements bonded together by the ionic bonds.
(b)
Interpretation:
Oxygen,
Concept introduction:
An atom is a single entity there is no bonding for an atom alone. A molecule is the combination of two or more atoms of the same or different elements bonded together by a covalent bond. A formula unit is the combination of the atom of two or more elements bonded together by the ionic bonds.
(c)
Interpretation:
Plutonium(III) oxide,
Concept introduction:
An atom is a single entity there is no bonding for an atom alone. A molecule is the combination of two or more atoms of the same or different elements bonded together by a covalent bond. A formula unit is the combination of an atom of two or more elements bonded together by the ionic bonds.
(d)
Interpretation:
Hydrogen peroxide,
Concept introduction:
An atom is a single entity there is no bonding for an atom alone. A molecule is the combination of two or more atoms of the same or different elements bonded together by a covalent bond. A formula unit is the combination of the atom of two or more elements bonded together by the ionic bonds.

- Methyl isocyanate, , is an intermediate in the manufacture of many pesticides. It received notoriety in1984 when a leak from a manufacturing plant resulted in thedeath of more than 2000 people in Bhopal, India. What are thehybridizations of the N atom and the two C atoms in methyl iso-cyanate? Sketch the molecular shapearrow_forwardFor the Lewis electron dot formula for hydrogen carbon trichloride, HCCl3, there are ___Regions of Electron Density around the C and the shape is ___arrow_forwardWithout consulting any tables, arrange the following substances in order and explain your choice of order: (a) Mg2+,Ar,Br,Ca2+ in order of increasing radius (b) Na, Na+ , O, Ne in order of increasing ionization energy (c) H, F, Al, O in order of increasing electronegativityarrow_forward
- Why do nonmetals tend to form anions rather than cations?arrow_forwardAluminum oxide (Al₂ O₃) is a widely used industrial abrasive(emery, corundum), for which the specific application depends onthe hardness of the crystal. What does this hardness imply about the magnitude of the lattice energy? Would you have predictedfrom the chemical formula that Al₂ O₃ is hard? Explain.arrow_forwardThe illustration to the left represents a mixture of xenon ( brown ) and fluorine ( green ) molecules.arrow_forward
- Combine two elements (cesium, berryllium, bromine, and flourine) from the following: ( K, Mg, Mn, N, O, Fe, Cu, H, S, Kr,C, Na, Br, Cl) to form 5 different molecules, including one oxy atomic moleculeand one diatomic molecule from the given elements(cesium, berryllium, bromine, and flourine), and determine the following: a) the electronegativity of the compound (show your calculation) b) Is the selected molecule polar, or not? What type of bond is formed based onwhat you learned? Is it a strong or weak bond?arrow_forwardIn which of the compounds CH4, NH3, H2O, SiH4, or H2S is δ+ for hydrogen the greatest? In which one does hydrogen bear a partial negative charge?arrow_forward(c) Theoretically, define the following elements in the formulae belowPth = ρghq x ŋarrow_forward
- For the Lewis electron dot formula for oxygen diiodide, OI2, there are ___ Regions of Electron Density around the O and the shape is ____arrow_forwardIn a lithium-ionbattery that is discharging to power a device, for every Li+that inserts into the lithium cobalt oxide electrode, a Co4+ion must be reduced to a Co3+ ion to balance charge. Usingthe CRC Handbook of Chemistry and Physics or other standardreference, find the ionic radii of Li+, Co3+, and Co4+. Orderthese ions from smallest to largest.arrow_forwardFor the group 6A elements, what is the trend in electronegativitywith increasing atomic number?arrow_forward
