Both types involve multiple atoms coming together to form a more complex structure.Both types of bonding result in atoms becoming more stable in the group than they were individually. Both types of bonding are exothermic as the potential energy of the participants is lowered as they form the bond. Ionic bonding occurs between atoms that have opposite needs for electrons (metals and nonmetals) and results in a transfer of electrons. Covalent bonding occurs between atoms that have similar needs for electrons (two nonmetals) and results in a sharing of electrons.

By transferring electrons, ionic bonding leads to the formation of charged particles that have either an excess of protons (cation) due to the loss of electrons or an excess of electrons (anion) due to the gain of electrons. Covalent compounds contain neutral atoms.The electrostatic attraction that occurs in ionic bonding is between cations and anions. The electrostatic attraction in covalent bonding arises from a shared electron’s attraction for its original nucleus as well as the nucleus of the sharing atom.

Ions bond in a pattern that maximizes attractions between oppositely charged ions and minimizes repulsions between like charged ions. The geometric pattern that arises is called the crystal lattice and is consistent throughout the crystal. All ions are held by a network of ionic bonds which are considered strong intramolecular forces. Atoms in a covalent compound are held together by covalent bonds which are also considered strong intramolecular forces. In the solid, crystalline state, both types lead to regular, ordered patterns and structures.

Both types of compounds can undergo changes in physical state under the right conditions of temperature and pressure.

Both types of compounds have a net neutral charge.

Both types of compounds contain a fixed ratio of participants that is represented by the subscripts in their chemical formulas (they do not require a 1:1 ratio).

Explanation:This was the exact assignment I had I got a 96%

most voltage drop calculators want the distance between the source and destination. then internally, they double it so both the source and return wires are calculated. but you need to know which distance the calculator uses so you're not half of what you should be or double what you should be.

most circuit breakers will not take a #6 directly, so the electrician will have to splice on a smaller pigtail. you also have to upsize the grounding wire when you upsized the ungrounded (hot) wire (see note in 250.122). this will preclude using most cable assemblies, as a cable with #6 copper will most likely only have a #10 grounding conductor. you need a #6 grounding conductor if the circuit is 20a. a #8 cable is no better, as it will have a #10 grounding conductor too. but most 20a breakers will take a #8 directly.

in your related post, you didn't say what type of load this is. if it is a light or heater, voltage drop won't be a big issue. if this is a motor, the current needs are huge at startup and the voltage drop can pose a problem. if this is a motor, knowing if the motor is under much load during startup will answer the voltage drop effect (a saw is easier to start than a compressor).
