What is a characteristic of each of the families on the periodic table?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.
What are the 5 families on the periodic table?
On the periodic table, there are families which are groups of elements with similar properties. These families are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases.
What are the 10 families of the periodic table?
Related elements, including the noble gases, halogens, alkali metals, alkaline earth metals, transition metals, lanthanides, and actinides. In addition, metals, nonmetals, and metalloids form loosely defined families. Other family designations—such as carbon family—are sometimes used.
What are the characteristics of the periodic table?
The periodic table is composed of seven horizontal rows or periods and is numbered between 1 to 7. There is a regular gradation in the properties of elements in the horizontal rows(periods) from left to right. The periodic table is composed of eight vertical columns or groups. They are numbered between 1 to 8.
What are Element families?
An element family is a set of elements sharing common properties. Elements are classified into families because the three main categories of elements (metals, nonmetals, and semimetals) are very broad.
What is a characteristic of the family in Group 17?
The halogens are the elements that form group 17 of the periodic table. They are reactive nonmetals and include fluorine, chlorine, bromine, and iodine. Halogens are highly reactive non-metals. These elements greatly resemble in property with each other.
What are element families?
What are the 9 families of the periodic table?
9 Element Families
- Alkali Metals: Group 1 (IA) – 1 valence electron.
- Alkaline Earth Metals: Group 2 (IIA) – 2 valence electrons.
- Transition Metals: Groups 3-12 – d and f block metals have 2 valence electrons.
- Boron Group or Earth Metals: Group 13 (IIIA) – 3 valence electrons.
How many families are in the periodic table?
In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the f-block columns (between groups 2 and 3) are not numbered.
What are the general characteristics of all the elements in group 18?
The noble gases are a group of chemical elements that make up Group 18 on the periodic table. These gases all have similar properties under standard conditions: they are all odorless, colorless, monatomic gases with very low chemical reactivity.
