Everything down the 2nd column (group) on the Periodic Table of elements. E.g. Be (berrylium), Mg (magnesium), Ca (calcium) and so on. When they "react", its because they either lose or gain or share their valance electrons. This is either ionic or covalent bonding.
Ionic bonding is when an atom "loses" one or more valance electrons to another atom. Covalent bonding is when two or more atoms "share" valance electrons. All atoms can do this, apart from the ones in the 18th group. These are called "inert gases" or "noble gases." They have full valence electron shells. The other elements only react with one another to lose or gain electrons, to form a full valance shell. Noble gases are ones like He (helium), Ne (neon) and Ar (argon).
The periodic table tells you that elements in the same group have similar chemical properties because they have the same number of valence electrons. This influences how they react with other elements and helps predict their behavior in compounds.
Elements in Group 16 of the periodic table usually have six valence electrons and are nonmetals. They tend to form -2 anions when they react with other elements. These elements are known as the chalcogens and include oxygen, sulfur, and selenium.
Elements in the same column on the periodic table share similar chemical properties because they have the same number of valence electrons. This allows them to form similar types of bonds and react in similar ways with other elements. The columns, or groups, are arranged based on the number of valence electrons in each element.
Reactivity generally increases as you move from right to left across a period and from top to bottom down a group on the periodic table. This is because elements on the left side of the table have fewer electrons in their outer shell, making them more likely to lose electrons and react with other elements.
The noble gases have a complete octet of valence electrons. This means they have a full outer electron shell, which makes them stable and less likely to react with other elements. Examples of noble gases include helium, neon, and argon.
the periodic table
The periodic table tells you that elements in the same group have similar chemical properties because they have the same number of valence electrons. This influences how they react with other elements and helps predict their behavior in compounds.
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
The noble gases family do not react with other elements since they have a full valence shell of electrons, making them stable and nonreactive.
Elements in Group 16 of the periodic table usually have six valence electrons and are nonmetals. They tend to form -2 anions when they react with other elements. These elements are known as the chalcogens and include oxygen, sulfur, and selenium.
Periodic trends affect how certain elements on the periodic table react with each other. For example, Ionization energy tend : metals want to give off electrons , non metals want to gain electrons. This trend is essentially which elements are likely to react together and how they would react together, which is essentially ion formation (gain or loss of electrons through a reaction).

Elements react with other elements based on the number of electrons in their outer shell, also known as valence electrons. Elements are most stable when their outer shell is full, so they will either gain, lose, or share electrons in order to achieve a full outer shell.
Elements in the periodic table have predictable chemical properties based on their position because they have the same number of valence electrons. This determines how they will react with other elements and molecules. The periodic table's structure helps scientists predict the behavior of elements based on their properties.
