How many covalent bonds would the element tellurium be expected to form in order to obey the octet rule?
2
Atoms with how many valence electrons will probably gain two electrons or share two covalent bonds?
Atoms with six valence electrons will likely gain two electrons or share two covalent bonds to achieve a full octet, as this will give them more stability by filling their outer shell.
What type of bonds does cadmium telluride have?
Cadmium telluride (CdTe) primarily forms ionic bonds. Cadmium atoms contribute positively charged ions (Cd^2+) while tellurium atoms contribute negatively charged ions (Te^2-), resulting in a strong ionic bond between the two elements.
How many valence electrons in Te?
Tellurium (Te) has six valence electrons.
Why do TeO2 bonds have unequal bond lengths unlike SO2?
TeO2 has unequal bond lengths because the central Te atom has a larger size than the surrounding O atoms, resulting in longer Te-O bonds than O-O bonds. In contrast, in SO2, the S atom is smaller than the O atoms, leading to more equal bond lengths. The size difference between the central atom and the surrounding atoms influences bond lengths in molecules.
