What else can I help you with?
Is the Iodine in period 2 of the periodic table?
No , Iodine is placed in period-5 of the periodic table.
A period is a horizontal row on the periodic table?
Actually, a period is a horizontal row on the periodic table that signifies the number of electron shells an atom possesses. Elements within the same period have the same number of electron shells but different numbers of electrons in their outermost shell.
How many elements are there in the first period of periodic table?
There are 2 elements in the first period of the periodic table: Hydrogen and Helium.
What period on the periodic table is barium?
Barium, atomic number 56, is in group 2 of period VI (six) in the periodic system.
What period is Florine in on the periodic table?
Period 2, Group 17
What are the allowed orbital types for the second period of the periodic table?
The allowed orbital types for the second period of the periodic table are s and p orbitals. This means that elements in the second period can have a maximum of 2 electrons in an s orbital and 6 electrons in p orbitals.
Why Lithium carbon And Neon Are Placed In Period 2 in periodic table?
Lithium, carbon, and neon are placed in period 2 of the periodic table because they all have 2 energy levels. Lithium has 2 electrons in its outer energy level, carbon has 2 electrons in its second energy level, and neon has a complete second energy level with 8 electrons. This pattern follows the periodic table's organization based on increasing atomic number and electron configuration.
What period of the periodic table is oxygen in?
Oxygen is in Period 2 , Group 16 ( VI A) of periodic table
Is the Iodine in period 2 of the periodic table?
No , Iodine is placed in period-5 of the periodic table.
Coulmns on a periodic table are called?
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".
Describe the number of valence electrons in each atom as you move down group 2 in the periodic table?
As you move down group 2 in the periodic table, the number of valence electrons in each atom remains the same, at 2. This is because elements in the same group have the same number of valence electrons, regardless of the period they are in.
How many shells are there in period 2?
There are two shells in period 2 (that's why it's named like that)The first can hold (max.) 2 electrons (1s2), the second holds 2+6 = 8 electrons (2s2 and 2p6) at maximum.
A period is a horizontal row on the periodic table?
Actually, a period is a horizontal row on the periodic table that signifies the number of electron shells an atom possesses. Elements within the same period have the same number of electron shells but different numbers of electrons in their outermost shell.
How many elements are there in the first period of periodic table?
There are 2 elements in the first period of the periodic table: Hydrogen and Helium.
What period on the periodic table is neon found?
Period 2
Which period in the periodic table does nitrogen belong to?
It is in period 2.
What period on the periodic table is barium?
Barium, atomic number 56, is in group 2 of period VI (six) in the periodic system.
