This element is chlorine and is very reactive.
Elements in the same column on the periodic table have similar chemical reactivity because they have the same outer electron configuration and it is the electron structure that determines an elements properties.
Electronegativity - capacity to loss electrons - is representative for the reactivity of chemical elements; for metals low electronegativity is a high reactivity.
Elements with the same number of valence electrons typically have similar chemical properties. This is because valence electrons determine an element's reactivity and bonding behavior. Elements in the same group on the periodic table have the same number of valence electrons.
the reactivity of depends on the number of its outer shell electrons. one all outer shell electrons are there then there is little reactivity. If the atomic number is 19 then the element will 19 protons and 19 electrons. this means it has 2 electrons in the 1st shell 8 in the second 8 in the 3rd and 1 in the last. as it only has one it will be very reactive =)
The number and arrangement of electrons determine how elements react chemically. Elements strive to achieve a stable electron configuration, such as a full outer electron shell, through gaining, losing, or sharing electrons with other elements. This determines an element's reactivity and chemical behavior.
Valence electrons determine the reactivity and chemical behavior of an element. Elements with the same number of valence electrons exhibit similar properties and tend to form similar types of chemical bonds.
Valence electrons determine an element's chemical properties, such as its reactivity and ability to form bonds with other elements. The number of valence electrons also influences the element's position in the periodic table and its likely bonding patterns.

The group number of A elements in the AB numbering system indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on. Valence electrons are important because they determine the chemical properties and reactivity of an element.
In a group, elements have the same number of outer shell electrons, which corresponds to the group number. For example, elements in Group 1 have 1 outer shell electron, elements in Group 2 have 2 outer shell electrons, and so on. This pattern helps determine the reactivity and chemical properties of elements within the same group.
True. Generally, the reactivity of metal elements increases as you move from left to right across the periodic table. This is because as you move towards the right, the elements have fewer electrons in their outer shell, making them more likely to lose electrons and react with other elements.
The number of electrons in an element determines its chemical properties and behavior. Specifically, it influences how an element will bond with other elements to form compounds and determines its reactivity.
