What else can I help you with?
Why do elements within a period of the periodic table have different properties?
They have different numbers of valance electrons...
As you move across a period elements have the same number of?
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
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,
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.
What period are the following elements?
period 3
What is another name for a cloumn of elements?

How are the elements in a period different?
By their atomic weight..protons and electrons.
Why do elements within a period of the periodic table have different properties?
They have different numbers of valance electrons...
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?

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.
What is periodisation of history of India?
The periodization of history of India has different elements. The period of 1500 - 1000 BC was called the Vedic period. The period of 322 - 187 BC was called the Mauryan period.
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.
Why do the properties of elements of change in a regular way across a period?
Because certain groups have different characteristics, so when you move to a different group the characteristics will be different.
As you move across a period elements have the same number of?
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
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?
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
