it is the very common atom Carbon.
---
The element could be carbon, if the four electrons are in the valence shell. However, if it is total of four electrons, then the element will be beryllium
None.
No , Iodine is placed in period-5 of the periodic table.
Period 2, Group 17
The periods mean the number of lines there are on the periodic table of elements.For example:Hydrogen is in period 1Iron is in Period FourThe periodic table includes ___ _______ periods.Answer:
it is in group, 4 and in period 2 group means how many electrons in outer shell, and period means how many electron shells it has:)
Yes, a period is a horizontal row on the periodic table.
The vertical columns of the periodic table are called groups. The horizontal rows of the periodic table are called periods. The number of electron shells an atom has corresponds to the number period of the periodic table it is located in. The oxidation number or number of valence electrons an atom is depicted by the group it is in. For example: Calcium (Ca) has an oxidation number of +2 and has 2 valence electrons( outermost electrons) which means it belongs to group 2 of the periodic table called the "alkali earth metals".
No , Iodine is placed in period-5 of the periodic table.
Oxygen is in Period 2 , Group 16 ( VI A) of periodic table
Period 2
It is in period 2.
Group 4 elements on the periodic table contain no period 2 elements whatsoever.
Group 2, period 2
Calcium has 20 electrons and has an atomic weight of 40.078 amu. It is in group 2, period 4 of the Periodic Table, and is a soft gray alkaline earth metal.
The periods mean the number of lines there are on the periodic table of elements.For example:Hydrogen is in period 1Iron is in Period FourThe periodic table includes ___ _______ periods.Answer:
Carbon is in period 2.
Period 2, Group 17
The element with atomic number 28 is Nickel (Ni). It is a transition metal in period 4 of the Periodic Table. It is the first element in the Nickel family. It has 28 electrons in 4 shells with 2 electrons in the outer shell.
