What element has 2 energy level and is in group 2?
All the numbers in the 2nd column (Group 2) have 2 electron in their outermost energy level. That would be elements such as Be (Beryllium), Mg (Magnesium), Ca (Calcium) and so forth.
What element is under 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 element in group 2 is most metallic?
Among the group 2 elements, radium is known to have the greatest metallic character and it can, therefore, be considered the most metallic group 2 element. This is because the metallic character of elements increases while traversing down a group, and radium is at the bottom of group 2 in the modern periodic table.
Which is the hardest element in group 2?
The sequence of the elements from top to bottom in the alkaline earth metal group – II is Be, Mg, Ca, Sr, Ba, Rb. Hence, going by the above explanation, the hardest alkaline earth metal is Beryllium (Be).
What is the least reactive element in group 2?
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 is the least metallic element in group 2?
In group 2 of the periodic table, the most metallic and least-metallic elements are Radium and Beryllium respectively.
Which alkaline earth metal is hardest?
Hardest element among alkaline earth metals is Beryllium.
What are the names of Group 2 elements?
Group 2 elements are: 1 Beryllium 2 Magnesium 3 Calcium 4 Strontium 5 Barium 6 Radium
What are the energy levels of each element?
Element Element Number Number of Number of Number of Protons/ Electrons Neutrons Energy Levels 2nd Level Hydrogen 1 1 0 Helium 2 2 2 Lithium 3 3 4
What is the fourth energy level of the periodic table?
Fourth energy level = 1, 2. Read more about the periodic table in the teacher background section. A certain number of electrons go into a level before the next level can have electrons in it. After the first energy level contains 2 electrons (helium), the next electrons go into the second energy level.
What are the properties of the same group of elements?
Each group of elements having the same number of valence electrons. The Same group elements have similar properties and reactivity. These elements tend to show patterns in atomic radius, ionization energy, and electronegativity.
