Feb 06, 2020 · As you move across a row of the periodic table, the ionic radius decreases for metals forming cations, as the metals lose their outer electron orbitals. The ionic radius increases for nonmetals as the effective nuclear charge decreases due to the number of electrons exceeding the number of protons.
Give an example of a molecule or ion for each shape. A molecule with the formula AB 3, in which A and B represent different atoms, could have one of three different shapes. Sketch and name the three different shapes that this molecule might have. Give an example of a molecule or ion that has each shape.
Apr 26, 2015 · A) square planar. The answer is A) square planar. Start from the Lewis structure of the tetrafluoroborate ion, BrF_4^(-). The molecule will have a total of 36 valence electrons - 7 from bromine, 7 from each of the four fluorine atoms, and one extra electron to give the ion the -1 charge. The bromine atom will be bonded to each of the four fluorine atoms via single bonds for a total of 8 of the ...
SHORT ANSWER Answer the following questions in the space provided. 1. a The notation for sodium chloride, NaCl, stands for one (a) formula unit. (c) crystal. (b) molecule. (d) atom. 2. d In a crystal of an ionic compound, each cation is surrounded by a number of (a) molecules. (c) dipoles. (b) positive ions. (d) negative ions.
The answer to the first question is that Earth has gotten older, and its age less approximate, the longer geologists have studied it (we now believe the earth is about 4.6 billion years old); the answer to the second question is the same for any science, qualitatively and quantitatively (or more accurately, by use of relative and absolute ...
Common table salt (NaCl) is a mineral composed of chlorine and sodium linked together by ionic bonds (Figure 1.4.1). The mineral name for NaCl is halite. An element like chlorine can also form bonds without forming ions.
Refer to the Hjulström-Sundborg diagram in Figure 14.19 to answer these questions. A fine sand grain (0.1 mm) is resting on the bottom of a stream bed. What stream velocity will it take to get this sand grain into suspension? Once the particle is in suspension, the velocity starts to drop.
