what elements are in group 2

What Elements Are In Group 2? The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.

Which group of elements is in Group 2? alkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

What are the properties of elements in Group 2? Alkali Earth Metals – Group 2 Elements For a metal, alkali earth metals tend to have low melting points and low densities. Being a metal, they are obviously good conductors of heat and electricity. The general electronic configuration of Group 2 elements is ns2.

What element is in group 2 Period 2? Answer. Answer: Berilium. Berilium is located in period 2 group2.

Which element is in group 2 and period 3 of the periodic table?

Hence the name of the element is magnesium.

What element is in group 2 period 4?

The given element is calcium. The atomic number of calcium is 20. It is situated in the second group which is alkaline earth metals and in the fourth period. Therefore, calcium is the correct answer.

Which element in group 2 is most reactive?

The alkali metals are the most reactive metals. Group 2 consists of the alkaline Earth metals. They are very reactive but less so than the alkali metals.

What element is in group 2 period 6?

Barium is a chemical element with the symbol Ba and atomic number 56. It is the fifth element in Group 2, a soft silvery metallic alkaline earth metal.

Is in group 2 and in the second period?

The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon. In a quantum mechanical description of atomic structure, this period corresponds to the filling of the second (n = 2) shell, more specifically its 2s and 2p subshells.

Why are group 2 called alkaline earth?

Group 2 elements except beryllium are known as alkaline earth metals. These are so called because their oxides and hydroxides are alkaline in nature and these metal oxides are found in Earth.

Which elements in Period 2 are nonmetals?

C , N, O and F are non metals present in period 2 while Na , Mg and Al are metals in period 3.

What element is in period 2 Group 18?

NEON is a noble gas which is in GROUP 18 AND PERIOD 2.

What element is in period 2 Group 17?

Group 17 occupies the second column from the right in the periodic table and contains fluorine (F), chlorine (Cl), bromine (Br), iodine (I), astatine (At), and tennessine (Ts).

What is a metalloid in period 2?

The only metalloid that is located at period 2 is boron (B).

What is the alkali metal in period 2?

According to this, period 2 alkali metal is Li.

Which elements in Period 2 are metals?

The elements in the second period are Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine and neon. Among this, Lithium and Beryllium are the elements that are metals.

Which element in group 2 is most likely to lose an electron?

Answer: In particular, cesium (Cs) can give up its valence electron more easily than can lithium (Li). … The same trend also is seen among the Group 2 elements (the alkaline-earth metals); the farther down in the group the metal resides, the more likely it is to lose an electron.

Which metal in group 2 is least reactive?

The least reactive element in group 2 is beryllium. Even at red heat beryllium will not react with water and it does not react with dinitrogen (N2).

What do group 2 elements react with?

Group 2 elements (beryllium, magnesium, calcium, strontium and barium) react oxygen. to generate metal oxides. This Module addressed why it is difficult to observe a tidy pattern of this reactivity.

What element is in Period 2 Group 16?

oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).

What is Group 2 called?

The Group 2 alkaline earth metals include Beryllium, Magnesium, Calcium, Barium, Strontium and Radium and are soft, silver metals that are less metallic in character than the Group 1 Alkali Metals.

How many valence electrons do the group 2 elements have?

Thus, the element in the second group of the periodic table will have an outermost s orbital filled with two electrons of different spins. Hence, the number of valence electrons in group 2 is two.
