1. Based on their positions on the Periodic Table, which ONE of the following elements would be expected to have the largest first ionization energy? A) Si B) K C) O D) As E) Ca 2. Based on their positions on the Periodic Table, rank these ions in order of decreasing ionic radius: F–, Mg2+, Na+, O2–, S2–. (The correct answer has largest ion first, smallest ion last.) A) S2– > O2– > F– > Na+ > Mg2+ B) O2–...
A magnesium ion, Mg2+, with a charge of 3.2×10−19C and an oxide ion, O2−, with a charge of −3.2×10−19C, are separated by a distance of 0.40 nm. How much work would be required to increase the separation of the two ions to an infinite distance?
In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.07×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.)
In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 1.81×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.)
Which of the following pairs are NOT isoelectronic? N3- and P3- S2- and Cl- F- and Mg2+ Na+ and O2-
Predict the larger ion in each of the following pairs. (a) Naor Mg2+ (b) Co2+ or C03+ (C) N3- or N (d) $2 or 02- Submit Answer 5 question attempts remaining
In a magnesium oxide unit, the distance between the magnesium ion (Mg2+) and the oxide ion (O2−) is 2.13×10-10 m. Calculate the work required to separate the two ions to an infinite distance apart. (Model the ions as point charges at rest before and after the separation.) If you could do this without using Calculus that would be great.
