low I.E., high I.E

Explanation:

Ionic or electrovalent bonds are interatomic bonds that results from the transfer of electrons between atoms. It is usually between a metal, electron donor, and non-metals which accepts electrons readily.

For an ionic bond to be formed, a large electronegativity difference is required. This suggests that one atom has a large electronegativity value while the other, the donating atom, has a low value of electronegativity. Electronegativity of an element is a property that combines the ability of its atom to lose or gain electrons. So, with respect to electronegativity, atom X would have a low electronegativity value and Y, a very high electronegativity value.

Ionization Energy(I. E) is the readiness of an atom to lose an electron. Most metals have low I.E values and would readily want to lose electrons. This satisfies X. Y in an ionic bond would have a very high I.E value and would not readily want to lose electrons but gain electrons. Y is a non-metal to a large extent.

explanation:

the largest database of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. the number of potential organic compounds has been estimated at 1060—an astronomically high number. the existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. the simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. in addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory. we use hydrocarbons every day, mainly as fuels, such as natural gas, acetylene, propane, butane, and the principal components of gasoline, diesel fuel, and heating oil. the familiar plastics polyethylene, polypropylene, and polystyrene are also hydrocarbons. we can distinguish several types of hydrocarbons by differences in the bonding between carbon atoms. this leads to differences in geometries and in the hybridization of the carbon orbitals.

the wheels would then hit the curb if it started to rolling, decreasing the chance of an accident.
