Which type of orbital is not allowed?
Which type of orbital is not allowed? The answer is d) 2d. Without going into too much detail, the 2d orbitals cannot exist because they are not allowed solutions to the Schrodinger equation. Simply put, the second energy shell, designated by a principal quantum number equal to 2, or n=2 , can only hold s […]
Which is older intrusion or extrusion?
Which is older intrusion or extrusion? Lava that hardens on the surface is called an extrusion. The rock layers below an extrusion are always older than the extrusion. There, the magma cools and hardens into a mass of igneous rock called an intrusion. An intrusion is always younger than the rock layers around and beneath […]

What is a high resistance wire?
What is a high resistance wire? Resistance wire is used to control the amount of current in a circuit. High resistivity is better since a shorter wire can then be used. When it is used for heating elements for applications such as electric heaters and toasters, high resistivity and oxidation resistance is important. What’s the […]
