As you go down the group, energy levels are being added with each period, and the valence electron is farther away from the nucleus, and is therefore held less tightly. So it is easier for the single electron to be removed, forming a positively charged ion of 1+.
In the periodic table, a group is a vertical column of elements that share similar chemical properties due to having the same number of valence electrons. There are 18 groups in the modern periodic table, each with its own unique characteristics and reactivity patterns. Examples of groups include the alkali metals (Group 1) and the halogens (Group 17).
Xenon belongs to the noble gas family (group 18) on the periodic table. Noble gases are characterized by their stability and lack of reactivity due to a full valence electron shell.
The nuclear charge decreases as you move down a group in the periodic table.
Yes, there is a relationship between an element's position in the periodic table and its chemical reactivity. Elements on the left side of the periodic table (Group 1 and 2) tend to be more reactive because they readily lose electrons to form positive ions. Elements on the right side of the periodic table (Group 17 and 18) tend to be less reactive as they have a full outermost electron shell.
Yes, reactivity generally increases as you move down a group in the periodic table due to the increase in the number of electron shells, which leads to a greater distance between the outer electrons and the nucleus, making it easier for the outer electrons to be involved in chemical reactions.
Chemical reactivity first decreases.then it increases as we move across a period.
Some good questions about periodic table: where are metalloids placed? why group 18 elements are inactive? How many groups and periods are in periodic table? How reactivity changes across and down the group?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
