They all have a filled 1s orbital
What else can I help you with?
The short periods contain some of the most common elements found in?
earths crust , oceans and atmosphere
Do elements in the same group or elements in the same period have more in common?
Elements in the same group have more in common because they have the same number of valence electrons, leading to similar chemical properties. Elements in the same period have increasing atomic numbers and electron shells, but their properties can vary widely due to different numbers of electron shells and arrangements.
Why are the elements on the periodic tables separated into periods?
The elements on the periodic table are separated into periods based on the number of electron shells they have. Elements in the same period have the same number of electron shells, which influences their chemical properties and reactivity.
How many peroids are in the periodic table of elements?
There are 18 periods in the periodic table. The periods are divided according to the chemical properties of elements. Elements in a group have similar properties.
What do rows have in common in the periodic table?
Elements of same row has equal number of shells.
Why some of the periods have different numbers of elements?
The early periods have less elements because they are filling up energy levels which hold only a few electrons. The later periods contain elements with electrons in levels with a greater capacity.
How many elements are in periods 6?
there are 32 elements in period 6.
How many elements are in periods 4?
There are 18 elements in period 4.
What relationship exists between elements and periods according to the periodic law?
The relationship between elements and periods according to the periodic law is that elements are arranged in periods based on their atomic number and properties. Elements in the same period have the same number of electron shells, while elements in the same group have similar chemical properties.
What do we call the horizontal row in the periodic table of elements?
Horizontal rows are called periods. There are 7 periods in periodic table.
How many periods of elements are there?
The periodic table of Mendeleev has 18 groups and 7 periods.
Which 2 periods have the same number of elements on the periodic table?
These are the periods 4 and 5.
