Learn the alkali metals definition, alkali metals properties, characteristics of alkali metals, and why alkali metals are so reactive. Related to this QuestionWhy are alkali metals more reactive than alkaline-earth metals? Why are metals more reactive in acids? Why is potassium the most reactive m...
What are the moderately reactive metals ? View Solution Explain by giving one example, how highly reactive metals (which are high up in the reactivity series) are extracted. View Solution View Solution View Solution View Solution View Solution ...
Metals and nonmetals differ in three main characteristics. First, metals are highly lustrous while nonmetals are either dull or not lustrous. Metals are also malleable, able to be shaped, while nonmetals can be brittle. Finally, metals are conductors while nonmetals are insulators....
Step 1: Identify the properties of alkali metals- Softness: Alkali metals are known for being soft and can be easily cut with a knife. This is true for all alkali metals.- Reactivity: Alkali metals are highly reactive, especially with water, and they tend to lose their outermost electron ...
Alkali metals are the elements of group 1 of the periodic table that when reacts with water, produces an alkaline solution, along with the release of hydrogen gas. Alkali metals include lithium, sodium, potassium, rubidium, and cesium.
Class D fires involve flammable metals. This is a special class of fire which is usually isolated to industrial scenarios, but burning metals can be extremely destructive and hard to control. Potassium, sodium, lithium and magnesium are highly reactive metals with explosive properties. Lithium is ...
heavy metalshyperaccumulatorsmessenger RNASome heavy metals (HM) are highly reactive and consequently can be toxic to living cells when present at high levels. Consequently, strategies for reducing HM toxicity in the environmental must be undertaken. This work focused on evaluating the Nickel (Ni) ...
Elements may be classified as metals, nonmetals or metalloids. Metals are the elements located at the left portion of the periodic table while the nonmetals are on the right side. The metals and nonmetals are separated by the metalloids. Answer and E...
Hydrogen has no neutrons, helium has two, lithium has four and beryllium has five, and the masses of the elements increase in that order. Hydrogen and helium are gases, whereas lithium and beryllium are metals.The Periodic Table and the Masses of Elements You can easily identify the lightest...
Alkaline earth metals are elements have low densities, boiling points, and melting points. They are soft and pliable. Alkaline earth metals are highly reactive because of the way their valence electrons function.Answer and Explanation: Beryllium, magnesium, calcium, strontium, barium, and radium are...
