The group of elements with two valence electrons in each period is known as the alkaline earth metals. These elements include beryllium, magnesium, calcium, strontium, barium, and radium. They are located in group 2 of the periodic table.
Give the period and group in which each of these elements is found nitrogen sodium iodine and mercury?
Nitrogen is period 2, group 15. sodium is period 3 group 1, iodine is period5 group 17. mercury is period 6 group 12.
What are the criteria used to placed an element under it is group and period?
Elements are placed in a group based on their similar chemical properties, such as reactivity and valence electrons. Elements are placed in a period based on the number of electron shells they have. Each period corresponds to the electron shell number of the elements in that period.
Who contains all known elements and lots of information about the elements?

Which word or group of words is represented by the word period in the term periodic table?
The word "period" in the term "periodic table" represents the rows of elements in the table that share similar chemical properties. Each period corresponds to the number of electron shells in an atom.
What are bridge and typical elements in modern periodic table?
In the modern periodic table, a bridge is a group of elements that connects the main body of the table. These include elements such as lanthanides and actinides. Typical elements are the main group elements found on the left and right sides of the periodic table, and they generally display similar chemical properties within each group.
