What period are the following elements in HeGeRbI?
The elements H (Hydrogen) and He (Helium) are in the first period, Ge (Germanium) is in the fourth period, Rb (Rubidium) is in the fifth period, and I (Iodine) is in the fifth period.
What is the difference between period 4 and 5 on the periodic table?
There are 4 electronic shells in period 4 while there are 5 shells in period 5.Elements of period 4 are smaller in size as compared to elements of period 5.Example of period 4 element is potassium and period 5 element is tin.
How many elements occur in each of the first three periods or the periodic table?
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
How many elements make up period 6 in the periodic table?
There are 32 elements in the 6th period of the periodic table.
What is the correlation of a period number with the elements of that period?
The period number of an element corresponds to the energy level of its outermost electrons. Elements in the same period have the same number of electron shells. As you move from left to right across a period, the number of protons and electrons increases, resulting in higher effective nuclear charge, which affects the properties of the elements.

How many elements in the first period?
Period 1: 2 elements Period 2: 8 elements Period 3: 8 elements Period 4: 18 elements Period 5: 18 elements Period 6: 32 elements Period 7: 25 elements
What is an elements period?
A period is a row of elements
What are the following elements that are in the same period as magnesium?
Magnesium is in Period 3 of the periodic table. The elements in the same period as magnesium (atomic number 12) include sodium (11), aluminum (13), silicon (14), phosphorus (15), sulfur (16), chlorine (17), and argon (18). These elements share the same highest energy level, which is the third shell in this case.
The period of elements that are all radioactive?
All elements comprising the period 7 in the periodic table are radioactive. In total this period has 32 elements.
Are period 1 elements more electronegative than period 2 elements?
No, period 1 elements are not more electronegative than period 2 elements. Electronegativity generally increases across a period from left to right, so elements in period 2 are generally more electronegative than elements in period 1.
What elements belong to the first period?
There are two elements in the first period, hydrogen and helium.
How many elements occur in each of the first three periods or the periodic table?

How many elements make up period 6 in the periodic table?
There are 32 elements in the 6th period of the periodic table.
How many elements are there in third period?
8 elements
