Elements with two valence electrons are typically referred to as alkaline earth metals. This group includes elements such as beryllium, magnesium, calcium, strontium, barium, and radium. These elements are found in Group 2 of the Periodic Table and are characterized by their relatively low electronegativities and reactivity, often forming +2 oxidation states in compounds.
What else can I help you with?
Which two elements have 2 valence electrons for Alkaline metals?
Lithium and Sodium both have 2 valence electrons.
What are metals that have 2 valence electrons?
alkaline earth metals (group 2 elements) have two valence electrons
How many veilance electrons does radium have?
Radium is a group 2 element. All group 2 elements have 2 valence electrons. Thus, radium has 2 valence electrons.
A group of element that has 2 valene electrons are called what?
A group of elements with two valence electrons are called alkaline earth metals. This group includes elements like magnesium and calcium. These elements are highly reactive due to their tendency to lose their two valence electrons.
How many valence electrons do the elements is group two have?
Group II elements (also called alkaline earth metals), have two valence electrons. To fill their outer shell, they therefore become ions with two positive charges, such as magnesium: Mg -> 2e- + Mg2+
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
How many valence electrons do Cooper have?
Copper (Cu) has 2 valence electrons. It is located in the middle group of elements, called Transition Metals, and all transition metals have 2 valence electrons...hope that helped! =D
How many valence electron does calcium have?
Calcium has 2 valence electrons, like all Group 2 elements.
What does the group number of A elements in the AB numbering system tell about valence electrons?
The group number of A elements in the AB numbering system indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on. Valence electrons are important because they determine the chemical properties and reactivity of an element.

Which atoms have the same valence as helium?
Helium has 2 valence electrons. Group 2 elements (alkaline earth metals) also have 2 valence electrons.
What are elements with 1 or 2 electrons in the outer energy level called?
Group 1: have 1 valence electrons (half filled s orbital) Group 2: have 2 valence electrons (completely filled s orbital)
How do I find the valence electrons in an atom?
To find the valence electrons in an atom, look at the group number on the periodic table. The group number tells you how many valence electrons an atom has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
