the ones that have similar properties with each other, right?
Alkali metals are very reactive, easily react with water, the have the valence is +1, they doesn't exist free in the nature, etc.
Alkali metals and halogens.
In chemistry, a family is a group of elements that have similar properties and react in a similar way. There are 18 families in the periodic table, each with their own unique characteristics and trends. These families are commonly referred to as groups and are labeled from 1 to 18 on the periodic table.
the periodic table
Neon is actually a gas; one of the "Noble" or "Inert" gases, meaning that it does not react with other elements very easily, and it is found on the far right of the periodic table.
No
Noble gases are unique because they are very stable and do not easily react with other elements to form compounds. They have a full outer electron shell, making them very unreactive and inert. This stability sets them apart from other elements in the periodic table.
No.
Gold is a metal that does not react with bases. It is a noble metal, meaning it is resistant to corrosion and does not easily react with other substances.
Nonmetals that do not react naturally with other elements are inert. These nonmetals are called the noble gases and are in Group 18 (VIIIA) on the Periodic Table.
Periodic Table families are groups of elements on the table which react similarly due to having the save number of electrons in the outer shell. These are organized vertically for all non transition metals. i.e. Hydrogen is in the same family as the Alkali metals since it has 1 electron in the outer shell.
Yes, americium is a reactive element.
