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
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 period represents elements on the sun the most on the periodic table?
Period-1 represents elements of the sun. This period constitutes hydrogen and helium.
What is special about a period on the periodic table?
all elements in a period all have the same amount of shells example: all elements in period 1 has only 1 shell all elements in period 2 has 2 shells so the period number is the same as the number of shells in that period
How many elements in the original period table of elements?
103
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
How do the elements in the period you choose compare?
In a period of the periodic table, elements have the same number of electron shells but different numbers of electrons in their outer shell. As you move across a period from left to right, the number of protons and electrons increases, causing elements to become more electronegative and decrease in atomic radius. Additionally, elements within a period show a trend of increasing metallic to non-metallic properties.
What is the atomic radius of manganese and how does it compare to other elements in the periodic table?
The atomic radius of manganese is about 127 picometers. In the periodic table, manganese has a smaller atomic radius compared to elements in the same period but larger than elements in the same group.
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.
What do you focus on when you compare elements of a story?
similarities
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
Why did mendeleev chose to order the known elements by mass?
Mendeleev chose to order the known elements by mass because he observed that there was a pattern in the physical and chemical properties of elements when they were arranged by increasing atomic mass. This led him to develop the periodic table, where elements with similar properties were grouped together.
