Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
Reactivity increases as you move down Group 1 in the Periodic Table. This is because the outermost electron is farther from the nucleus, leading to a weaker attraction and easier loss of the electron to form a positive ion.
Down the group, the reactivity increases as the atomic size becomes larger and ionisation potential decreases.

What is a group in periodic table?
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).
What happens as you move down the family on a periodic table the reactivity?
As you move down a family on the periodic table, reactivity generally decreases. This is because the outermost energy levels are farther away from the nucleus and the electrons are shielded by more inner electrons, making it harder for the atom to react with other substances.
What family group on periodic table is xenon?
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.
Is there a relationship between an elements position in the periodic table and its chemical reactivity?
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.
What are groups in the periodic table?
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
What are some good questions about the periodic table?
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?

What is a group in a periodic table.?
A group in Periodic Table is the column of element in periodic table
Which group in the periodic table is known as the noble gases?
The noble gases are a group of elements in the periodic table known as Group 18. These gases are colorless, odorless, and have low reactivity due to their stable electron configuration. Examples include helium, neon, argon, krypton, xenon, and radon.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
What are groups in the periodic table?
Groups in the periodic table are vertical columns that contain elements with similar chemical properties. Elements in the same group have the same number of valence electrons, which determines their reactivity and chemical behavior. There are 18 groups in the periodic table.
Differences between alkil metals and halogens?
Alkali metals are a group of elements found in Group 1 of the periodic table, known for their high reactivity and tendency to lose an electron to form a positive ion. Halogens are a group of elements found in Group 17 of the periodic table, known for their high reactivity and tendency to gain an electron to form a negative ion. Alkali metals are metals, while halogens are nonmetals.
