In this episode, we are discussing alkali metals.Alkali metals, found in Group 1 of the periodic table, are characterized by having one electron in their outermost shell, making them highly reactive as they readily lose this electron. This shared electron configuration leads to similar chemical behaviours. When these metals react with water, they produce a metal hydroxide, melt due to the energy released, and float. Their reaction with chlorine forms a metal chloride that dissolves in water, while exposure to oxygen results in the rapid formation of a metal oxide, causing the metal to tarnish.Don't miss out on subscribing for more educational content tailored to help you succeed in your exams.

In this episode, we will discuss halogens.Halogens, also known as Group 7 elements, possess seven outer electrons which makes them highly reactive as they readily gain one electron to achieve a stable full outer shell. In their elemental state, halogens exist as diatomic molecules. They commonly form salts when reacting with metals by accepting an electron. A key trend within the group is that reactivity decreases as you move down the periodic table due to increasing atomic size and reduced nuclear attraction for an additional electron.Don't miss out on subscribing for more educational content tailored to help you succeed in your exams.

This episode provides a fundamental distinction between metals and non-metals based on their position in the periodic table and outer electron configurations. It highlights that metals, located on the left, tend to lose electrons to form positive ions, while non-metals, on the right, typically gain or share electrons. We further outline key physical properties that differentiate these two categories, such as melting and boiling points, conductivity, and state at room temperature. Consequently, the source offers a concise overview of the contrasting chemical behaviors and physical characteristics of metals and non-metals.Don't miss out on subscribing for more educational content tailored to help you succeed in your exams.

Atomic Structure: Chemical Formula ⚛️ GCSE Chemistry Learning & Revision
In this episode, we’ll explore how atoms from different elements join together to form compounds. We’ll discuss how these compounds have unique chemical formulae based on their constituent elements. Using analogies like Lego models, we’ll illustrate how different atomic combinations create distinct structures. Finally, we’ll examine sodium oxide (Na₂O) as a specific example, demonstrating how elements combine to form compounds with recognizable chemical formulas.Don't miss out on subscribing for more educational content tailored to help you succeed in your exams.

In this episode, we’ll explore the fundamental concepts of elements and atoms in chemistry. We’ll discuss how there are 118 known elements, each with a unique chemical symbol. We’ll also examine atoms as the basic units of elements and illustrate these ideas with examples like oxygen (O), iron (Fe), and cobalt (Co). Finally, we’ll highlight the connection between element names and their symbols, reinforcing key concepts in chemistry.Don't miss out on subscribing for more educational content tailored to help you succeed in your exams.
