Marie Sk_odowska Curie's revolutionary research laid the groundwork for our understanding of physics and chemistry, blazing trails in oncology, technology, medicine, and nuclear physics, to name a few. But what did she actually do?...

While most elements can easily be categorised as either metals or non-metals, a few have physical and chemical properties that are in between, which makes them harder to classify.

Dr. Forrester teaches about the discoveries of radioactive isotopes by Marie Curie.

There are some substances out there that really really really don't sit well with human beings. Here are 10 of the most dangerous.

Tests by a Swiss laboratory have found significant levels of Polonium on the clothing of late Palestinian leader Yasser Arafat. The test results will raise doubts about the 2004 death of Arafat, in which poisoning was initially ruled...

It explains occurrence, electronic configuration, atomic and ionic radii, ionization enthalpy, physical and chemical properties of GROUP 16 elements.

It's time to check out Group 16 on the periodic table, the chalcogens. This includes oxygen, sulfur, selenium, tellurium, polonium, and livermorium. What can we say about their properties, reactivities, and applications? Let's find out!

The video is a lecture on nuclear equations, which explains how radioactive decay can be written in the form of an equation. The lecturer describes the symbols for alpha and beta particles and demonstrates how to balance equations on...

We've learned a lot about covalent compounds, but we haven't talked quite as much about ionic compounds in their solid state. These will adopt a highly ordered and repeating lattice structure, but the geometry of the lattice depends...

Event: October 1921. Scientist Marie Curie, winner of two Nobel prizes, visits the White House to accept a gift of one gram of radium. Story: Marie Curie worked hard to study science and was sometimes rejected because of her gender. She...

This video is a lesson about the life and achievements of Marie Curie, a pioneering female scientist. It covers her early life in Poland, her struggles to pursue education in France, her marriage to Pierre Curie, and their joint research...
