What type of bond is most likely being represented in row 1?

B

Which metal most likely has the highest thermal conductivity?

Diamond is the leading thermally conductive material and has conductivity values measured 5x’s higher than copper, the most manufactured metal in the United States. Diamond atoms are composed of a simple carbon backbone that is an ideal molecular structure for effective heat transfer.

What properties do metals exhibit as a result of having delocalized valence electrons?

Metallic Properties In a metal, atoms readily lose electrons to form positive ions (cations). These ions are surrounded by delocalized electrons, which are responsible for conductivity. The solid produced is held together by electrostatic interactions between the ions and the electron cloud.

Why is the current in a series circuit the same?

The amount of current in a series circuit is the same through any component in the circuit. This is because there is only one path for current flow in a series circuit.

Is current the same everywhere in a parallel circuit?

In parallel circuits the current splits up so each branch has a different effective resistance (in each of the separate branches one can use the series rule again). Due to this, the current isn’t the same everywhere in a parallel circuit. Most basic concepts that must be understood here are “Voltage” and “Current” .

What happens to the current in a parallel circuit when more bulbs are added?

As more bulbs were added, the current increased. As more resistors are added in parallel, the total current strength increases. The overall resistance of the circuit must therefore have decreased. The current in each light bulb was the same because all the bulbs glowed with the same brightness.

How does current split at a junction?

Current splits at a junction and voltage drops in series. The inherent property of electrons is to find a path of lowest possible resistance. Thus current always flow in a direction of lowest possible resistance path. Current will split in ratio depeding on the resistance of each possible path.

Which is better a series circuit or a parallel circuit?

Two bulbs in a simple parallel circuit each enjoy the full voltage of the battery. This is why the bulbs in the parallel circuit will be brighter than those in the series circuit. Another advantage to the parallel circuit is that if one loop is disconnected, then the other remains powered.
