How Many Valence Electrons Does Element-43, Otherwise Called Technetium, Have? Prairie Dog Control: Non-Lethal Techniques. Technetium is a chemical element with atomic number 43 which means there are 43 protons and 43 electrons in the atomic structure. Favorite Answer. A low resistivity indicates a material that readily allows the flow of electric current. Which elements woukd you expect to be similar to technetium?

Conductors are made of high-conductivity materials such as metals, in particular copper and aluminium.

We are a great educational resource!

m. Electrical resistivity and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. A lithium atom has one outer shell electron, so it’s usual valence is +1, but it can lose the electron and have a valence of -1. Semiconductors are materials, inorganic or organic, which have the ability to control their conduction depending on chemical structure, temperature, illumination, and presence of dopants.

Note that, electrical resistivity is not the same as electrical resistance. This database focuses on the most common chemical compounds used in the home and industry. Looking Good, Feeling Bad; or, What's the Problem with Perc?
