Interpretation:
The models representing the formation of positive calcium ion and negative bromide ion needs to be represented.
Concept introduction:
Chemical compounds are formed when the atoms, ions or molecules of two substances are attracted towards each other forming a

Answer to Problem 6SSC
The Calcium ion is formed by absorbing energy and Bromide ion is formed by releasing energy.
Explanation of Solution
The electronic configuration of Calcium is
Figure 1
The electronic configuration of Bromine is
It can be noted that Bromine has 7 electrons and requires one more electron to fill its octet structure. For addition of electron, it releases energy to form Bromide ion.
Figure 2
The Calcium ion is formed by absorbing energy and Bromide ion is formed by releasing energy.

- In the solid state, oxalic acid occurs as a dihydrate with the formula H2C2O4 C+2H2O. Use this formula to calculate the formula weight of oxalic acid. Use the calculated formula weight and the number of moles (0.00504mol) of oxalic acid in each titrated unknown sample recorded in Table 6.4 to calculate the number of grams of pure oxalic acid dihydrate contained in each titrated unknown sample.arrow_forward1. Consider a pair of elements with 2p and 4p valence orbitals (e.g., N and Se). Draw their (2p and 4p AO's) radial probability plots, and sketch their angular profiles. Then, consider these orbitals from the two atoms forming a homonuclear л-bond. Which element would have a stronger bond, and why?
