Answer:
The addition or subtraction of an electron and change ions to have a positive or negative charge. So, if and ion with an equal amount of protons and electrons gains an electron, it becomes negatively charged.
Explanation:
A double covalent bond.
<h3>Explanation</h3>
As their name suggest, ionic bonds are forces between ions of opposite charges. Ionic bonds involve the transfer of electrons from one atom to another. Such transfer can't occur between two carbon atoms. They belong to the same element and have the same tendency to gain or lose electrons. As a result, the bond between them cannot be ionic.
Ion dipole is a force <em>between</em> an ion and a molecule. The bond between the two carbon atoms is located <em>within</em> an organic molecule. The force between the two carbon atoms can't be ion dipole, either.
There are four valence electrons in each carbon atom. Each of them needs four more electrons to achieve an octet. They would achieve that octet by sharing four electrons with other atoms. Each shared electron pair acts as a covalent bond. Each hydrogen atom demands one more electron and would share only one electron with the carbon atom. The first carbon atom in this question shared two electrons with two hydrogen atoms. It needs to share two more with the other carbon atom so that it could achieve an octet. As a result, it would share two pairs of electrons, which will make a double covalent bond between the two carbon atoms.
Two or more orbitals that have the same energy are called degenerate orbitals. Those orbitals are different in a way that they are displayed differently in space around nucleus, but they are associated in the same energy. E.g., the three subshells of p orbital are px, py, and pz.
Answer:
B
Explanation:
Miscibility is the property of two substances to mix in all proportions (that is, to fully dissolve in each other at any concentration), forming a homogeneous mixture (a solution). The term is most often applied to liquids but also applies to solids and gases.
