Question

Bond character for GaBr

Answer 1

Ionic and covalent character describe the nature of the bond between atoms. For example, a molecule with a higher ionic character than covalent character means that the atoms have more of a give-and-take relationship for the electrons that bond them

Example of a polar covalent bondWhen a carbon atom forms a bond with fluorine, they share a pair of electrons. However, because fluorine is more highly electronegative than carbon, it attracts that shared electron pair closer to itself and thus creates an electric dipole. The lowercase greek delta written above the atoms is used to indicate the presence of partial charges. This bond is considered to have characteristics of both covalent and ionic bonds.

Though ionic and covalent character represent points along a continuum, these designations are frequently useful in understanding and comparing the macroscopic properties of ionic and covalent compounds. For example, ionic compounds typically have higher boiling and melting points, and they are also usually more soluble in water than covalent compounds.

Answer 2

The connection character between Ga and Br is ionic.

Step-by-step explanation:

Gallium is a chemical element with symbol Ga, with atomic number 31 (31 protons and 31 electrons), while bromine is a chemical element with symbol Br, atomic number 35 (35 protons and 35 electrons).

In order to know how the connection between these two elements will be, we will first need to know their electronic configurations.

The electronic configuration of Gallium is 3d¹⁰ 4s² 4p¹, while the electronic configuration of Bromo is 3d¹⁰ 4s² 4p⁵. With that, we can see that Gallium is a cation and has 3 electrons in its last layer, while Bromine is an anion that has 7 electrons in its last layer. Therefore, the bond between these two atoms will have an ionic character, where Gallium will lose three electrons that will be gained by Bromine, thus allowing these two atoms to enter into stability.
