What family of elements in the period table contains the most reactive metals?
The most reactive metals are the alkali metals in group 1a.
What are the Group 1A and Group 7A elements examples of?
Sodium and Chlorine = Sodium Chloride Potassium and Iodine = Potassium Iodide
What element from Group 1A is most reactive?
francium
What group of elements on the periodic table is most reative?
The alkali metals group, located in Group 1 of the periodic table, is the most reactive group of elements. These elements have one electron in their outermost shell, making them highly reactive as they seek to lose this electron to achieve a stable electronic configuration.
What Group 1A elements is the most reactive cesium potassium lithium or sodium?
Cesium is the most reactive Group 1A element because it has the lowest ionization energy and the largest atomic radius, making it more willing to donate its outermost electron in a chemical reaction compared to potassium, lithium, and sodium.
What are some of the elements are found in group 1A?
Some elements found in group 1A of the periodic table include lithium, sodium, potassium, rubidium, cesium, and francium. These elements are known for being highly reactive and easily forming ions with a +1 charge. They are typically stored under oil to prevent reaction with moisture in the air.
Which element in 1a group is more reactivity?
Francium(Fr) is the most reactive element in Group 1A . The least reactive is Lithium(Li) The element become increasingly reactive 'down' Group 1A. NB You will NOT find francium in a school lab. for two reasons. 1. It explosive when in contact with water. 2. It is 'Radio-active' and radio-active matter has to be kept in special conditions.
Is it true the group 1A elements except for hydrogen are known as the alkali metals?
Yes, that's correct. The elements in group 1A, excluding hydrogen, are known as the alkali metals. These metals include lithium, sodium, potassium, rubidium, cesium, and francium. They are highly reactive and typically have one electron in their outermost shell.
Why hydrogen placed with the elements in group 1A?
Hydrogen is placed with the elements in group 1A (1) because it has one electron in its outermost shell, similar to other group 1A elements like lithium, sodium, and potassium. However, hydrogen is unique as it is not a metal like the other elements in this group, exhibiting properties of both metals and nonmetals.
What is the most reactive element in group 1A?
If I recall correctly, it's because they don't have any electrons in their atoms. Atoms react in order to get a full set of 8 electrons, and the less electrons an atom has, the more likely they are to react.
How do 1A and 2A differ from the other group A elements?
bilat
What are the elements in groups 1A to 8A called?
The elements in groups 1A to 8A are called the representative elements or main group elements. Each group corresponds to a specific column on the periodic table and has similar chemical properties due to their electron configurations.
