FAQs on Alkaline Earth Metal Trends Video Lecture - Chemistry Class 11 - NEET

1. What are alkaline earth metals?
Alkaline earth metals are a group of elements in the periodic table consisting of beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). They are called alkaline earth metals because they are reactive and have properties similar to alkaline metals, but are less reactive.
2. What are the common trends among alkaline earth metals?
Common trends among alkaline earth metals include having two valence electrons, forming 2+ cations, and increasing atomic radius down the group. They also have similar chemical properties, such as forming oxides and hydroxides that are alkaline in nature.
3. How do alkaline earth metals react with water?
Alkaline earth metals react with water to form metal hydroxides and hydrogen gas. The reactivity increases down the group, with beryllium being the least reactive and barium being the most reactive. The reaction becomes more vigorous as you go down the group.
4. What are some common uses of alkaline earth metals?
Alkaline earth metals have various uses in different industries. For example, magnesium is used in the production of lightweight alloys for aircraft and automobile parts. Calcium is essential for building strong bones and teeth in humans and animals. Barium compounds are used in the medical field for X-ray imaging.
5. Why are alkaline earth metals less reactive than alkali metals?
Alkaline earth metals are less reactive than alkali metals because they have a higher ionization energy and a smaller atomic radius. This means that it takes more energy to remove an electron from an alkaline earth metal, making them less likely to form positive ions. Additionally, their outermost electrons are further away from the nucleus, resulting in weaker attraction and less reactivity.
