Zoom, Teams, Webex, Blue Jeans... We've all had to adapt ourselves to making more productive web calls over the last year. And, as a speaker, presenter, coach, and trainer, I've had more immersion in...

The magnetic quantum number  abbreviated as m  represents the orbital orientation of an electron in a given energy level and sublevel. Here's a thorough rundown:

An important idea in atomic theory is the Aufbau Principle, which shows how electrons are arranged in an atom. It says that electrons fill atomic orbitals from least energetic to most energetic, starting with the least...

Bohr's atomic model postulates that the radius of an electron's orbit around the nucleus is determined by the concept that electrons travel in quantised orbits with distinct and well-defined radii. According to the model, the angular...

Band Theory Dissection: Conduction in Various Substances

The band theory of solids is a fundamental concept in solid-state physics that explains the conduction of electricity in substances based on the arrangement of energy levels...

In part two of our series on Theory of Everything, we explain particle physics using string theory.

NaCl forms when sodium transfers an electron to chlorine, creating Na⁺ and Cl⁻ ions that attract each other to form a stable ionic lattice.

The Kossel-Lewis approach introduced the concept of ionic and covalent bonds. It emphasizes the role of electron transfer or sharing between atoms to achieve noble gas configurations

Photoelectric effect occurs when electromagnetic radiation above the threshold frequency of the given metallic surface, strikes the surface and releases electrons from it. This happens because light is made of massless particles called...

Valence electrons are the electrons in the outermost energy level of an atom. They are important because they are involved in the chemical bonding of our elements which helps determine the reactivity of elements. In order to be stable,...

A set of well-defined lines within the electromagnetic spectrum, emitted by hot or excited matter.

Exploring the science behind fireworks, discover how different elements are used to produce different colours of fireworks. Chemistry - Atoms And Bonding - Learning Points. In the mid-19th century the inventor if the Bunsen burner,...

We use a Bunsen burner to burn different chemical salts to see how the flame colour changes. This shows that sodium burns with a yellow flame, lithium burns with a red flame, barium burns with a yellow-green flame and copper burns with a...

By the end of this learning object, the student will be able to: Revise the elements and the components of the atom.14002

Today, we are exploring how to avoid sleep while studying. This video covers effective techniques to stay awake, focused, and energized during long study sessions. We’ll discuss practical tips like creating a conducive environment,...

We all have times when our energy levels are high. And others when we are feeling dull and slow. These are your energy cycles. And knowing what your energy cycle is can help you to plan and use your time most effectively.

Learn about the Periodic Table's Transition Metals with Transition Metals by KLT.

Today I’m talking about how to stay motived and positive while you’re stuck at home. This is based on a viewer question from Kelly. She asked how should she deal with fluctuating mood and energy levels in this time of...

6 Ways I Effectively Manage My Focus as a Woman with ADHD

This video mostly goes over two of the biggest classes and fields you learn about as a physics undergrad which is quantum physics and classical physics. I will be going over more classes (in less detail) and more...

This video provides an overview of the structure and notation of atoms, including the positively charged nucleus, negatively charged electrons, protons, neutrons, and the arrangement of electrons in energy levels. It also explains how to...

This nugget explains the features and mathematical expressions of Bohr's model and its advantages over Rutherford's model.

It explains types of molecular orbital's, contours and energies of bonding and anitbonding molecular orbitals.

Face the fact…you don't have a choice about pursuing goals. All humans were born to set and achieve meaningful goals. It’s not a question about whether to make goals or not, but which goals you should pursue! It’s a fact that the clearer...
