ESSENTIAL PREP FOR THE ACS GENERAL CHEMISTRY 1
EXAM: PRACTICE AND TIPS
Ion - CORRECT ANSWER✔✔A species of an element in which the number of electrons does not equal the number of protons.
Isotope - CORRECT ANSWER✔✔Each isotope of an atom has a different number of neutrons.
Isoelectric - CORRECT ANSWER✔✔Two atoms with the same charge.
Isotopic - CORRECT ANSWER✔✔Two atoms with the same number of neutrons.
Transition Metal Orbitals - CORRECT ANSWER✔✔The 4s orbital is filled before the 3d orbital, but listed after.
Paramagnetic - CORRECT ANSWER✔✔Atoms that possess a permanent magnetic charge due to the presence of unpaired electrons.

Electropositive - CORRECT ANSWER✔✔Tending to lose electrons and form positive ions.
Tetrahedral Bond Angle - CORRECT ANSWER✔✔109.5°
Resonance Structures - CORRECT ANSWER✔✔Two equally correct arrangements of one molecule's electrons; generally the molecule exists as an average
of the two.
Polar Molecule - CORRECT ANSWER✔✔A molecule that is mostly positive on one side and mostly negative on the other.
sp³ Orbital - CORRECT ANSWER✔✔An orbital composed of one s orbital and three p orbitals; can hold eight total electrons. Tetrahedral.
Trigonal Planar - CORRECT ANSWER✔✔The way that three objects will arrange themselves around a central atom. Non-polar.
Free Radicals - CORRECT ANSWER✔✔Compounds with an odd number of electrons in their Lewis Structure. Eg. NO₂
Incomplete Octets - CORRECT ANSWER✔✔Occur in elements that can form stable bonds with less than eight electrons. Eg. BF₃
