Questions and Corresponding Answers
with Surety of 100% Pass Mark
Ion - 🧠ANSWER ✔✔A species of an element in which the number of electrons
does not equal the number of protons.
Isotope - 🧠ANSWER ✔✔Each isotope of an atom has a different number of
neutrons.
Isoelectric - 🧠ANSWER ✔✔Two atoms with the same charge.
Isotopic - 🧠ANSWER ✔✔Two atoms with the same number of neutrons.
Transition Metal Orbitals - 🧠ANSWER ✔✔The 4s orbital is filled before the 3d
orbital, but listed after.
Paramagnetic - 🧠ANSWER ✔✔Atoms that possess a permanent magnetic charge
due to the presence of unpaired electrons.
Electropositive - 🧠ANSWER ✔✔Tending to lose electrons and form positive ions.
Tetrahedral Bond Angle - 🧠ANSWER ✔✔109.5°
Resonance Structures - 🧠ANSWER ✔✔Two equally correct arrangements of one
molecule's electrons; generally the molecule exists as an average of the two.

, Polar Molecule - 🧠ANSWER ✔✔A molecule that is mostly positive on one side
and mostly negative on the other.
sp³ Orbital - 🧠ANSWER ✔✔An orbital composed of one s orbital and three p
orbitals; can hold eight total electrons. Tetrahedral.
Trigonal Planar - 🧠ANSWER ✔✔The way that three objects will arrange
themselves around a central atom. Non-polar.
Free Radicals - 🧠ANSWER ✔✔Compounds with an odd number of electrons in
their Lewis Structure. Eg. NO₂
Incomplete Octets - 🧠ANSWER ✔✔Occur in elements that can form stable bonds
with less than eight electrons. Eg. BF₃
Expanded Octets - 🧠ANSWER ✔✔Occur in the third row of the periodic table and
beyond in elements that can form stable bonds with more than eight electrons.
Eg. XeF₂
Hydrogen Bonding - 🧠ANSWER ✔✔When hydrogen is attracted to
electronegative atoms.
Sigma Bonding - 🧠ANSWER ✔✔Formed by head-on overlapping between
orbitals.
