alkaline earth metals valence electrons have?

Elements of group 2 of the periodic table which are metals and has a shiny, silvery-white color are called alkaline earth metals. They have 2 electrons in their valence orbit/orbital. They are also highly reactive, but slightly less than the alkali metals.

Answer and Explanation: Lithium has one valence electron. It has a total of three electrons, with two in its first shell. All of the alkali metals have one valence electron,...

Similarly, all the alkaline earth metals react with the heavier group 15 elements to form binary compounds such as phosphides and arsenides with the general formula M3Z2. Higher lattice energies cause the alkaline earth metals to be more reactive than the alkali metals toward group 15 elements.

When valence electrons are farther from the nucleus, they are attracted less strongly by the nucleus and more easily removed from the atom. This makes the atom more reactive. ... This makes alkaline Earth metals with their two valence electrons less reactive than alkali metals with their one valence electron.

Magnesium has two valence electrons. Magnesium is element 12 and belongs to Group 2 of the Periodic Table. An element in Group 2 has two valence electrons.

Group 2A elements are the alkaline earth metals and all have two electrons in the outermost energy level because their electron configuration ends in s2. Group 5A elements all have five electrons in the outermost energy level because their electron configuration ends in s2p3.

Alkali metals have only 1 electron in its valence shell while alkaline earth metals have 2 electrons in its valence shell. Due to this reason, it becomes easier for alkali metals to loose an electron during a chemical reaction than that of alkaline earth metals which instead have to loose 2 electrons.

All alkali metals have one valence electron. ... The attraction from the positive nucleus to the negative electron is less. This makes it easier to remove the electron and makes the atom more reactive. Experimentally speaking, cesium (caesium) is the most reactive metal.

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

The number of valence electrons corresponds to the group number the element is in. In the case of potassium, it is a group 1 element and is part of the alkali metals. This means that potassium will have 1 valence electron.

Term. Alkaline earth metalsA group of chemical elements in the periodic table with similar properties: shiny, silvery-white, somewhat reactive at standard temperature and pressure. They readily lose their two outermost electrons to form cations with charge +2.

The alkaline earth metals are a group of elements in the periodic table. They are all in the second column of the periodic table. They are sometimes referred to as the group 2 elements.
978772
Explanation: The alkaline earth metals come from Group 2 of the Periodic Table. And since the Periodic Table reflects electronic structure, Be,Mg,Ca,Sr,Ba all have 2 valence electrons, and all commonly form M2+ ions.

Except for Be, all the alkaline earth metals react with N2 to form nitrides, and all react with carbon and hydrogen to form carbides and hydrides. Alkaline earth metals dissolve in liquid ammonia to give solutions that contain two solvated electrons per metal atom.

The second column on the periodic table of the chemical elements is collectively called the alkaline earth metal group: beryllium, magnesium, calcium, strontium, barium, and radium. Because the outer electron structure in all of these elements is similar, they all have somewhat similar chemical and physical properties.
