beryllium is denoted as Be, and is number 4, it is in group 2 and in period 2
There is no element with 28 protons in group 4. I think you are getting confused with group 4 and PERIOD 4. In period 4, the element with 28 protons is Nickel.
Germanium, belongs to period 4, group IVA (or group 14)
Ca or Calcium
Silicon is p-block element. It has 4 valence electrons. It is present in group-14.Titanium has 4 valence electrons. It is in the third period. Titanium is a metal element.
beryllium is denoted as Be, and is number 4, it is in group 2 and in period 2
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
That varies, element #3 will have 3, element 4 will have 4, etc. However, they all have 2 valence electrons.
Group 4 elements on the periodic table contain no period 2 elements whatsoever.
Ca (calcium)
There is no element with 28 protons in group 4. I think you are getting confused with group 4 and PERIOD 4. In period 4, the element with 28 protons is Nickel.
Br (Bromine) is a period 4 element in the same group as F.
No, it is an element of group 6 or VI-B of periodic table.
In the periodic table, the Group 2, Period 4 element is calcium. Calcium is classified as a silvery-gray metal. Calcium is the most abundant of the metallic elements in the human body.
Alkaline earth solid metal , group 2, period 2, atomic number 4
There is no such element on the Periodic Table
element K, or potassium
