What are the different groups on the periodic table?
What are the different groups in the periodic table of elements?
- Group 1: the alkali metals (lithium family) *not including hydrogen.
- Group 2: the alkaline earth metals (beryllium family)
- Groups 3-12: the transition metals.
- Group 13: the triels (boron family)
- Group 14: the tetrels (carbon family)
- Group 15: the pnictogens (nitrogen family)
- Group 16: the chalcogens (oxygen family)
What are the group numbers on the periodic table?
- Lithium (Li)
- Sodium (Na)
- Potassium (K)
- Rubidium (Rb)
- Cesium (Cs)
- Francium (Fr)
What are the groups and 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. The horizontal rows on the periodic table are called periods. Group (family): A vertical column in the periodic table.
What is Group 4 on the periodic table?
Group 4 is a group of elements in the periodic table. It contains the elements titanium (Ti), zirconium (Zr), hafnium (Hf) and rutherfordium (Rf). This group lies in the d-block of the periodic table. The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals.
What Is the Carbon Family?
The carbon family is element group 14 of the periodic table. The carbon family consists of five elements: carbon, silicon, germanium, tin, and lead. It is likely that element 114, flerovium, will also behave in some respects as a member of the family. In other words, the group consists of carbon and the elements directly below it on the periodic table. The carbon family is located very nearly in the middle of the periodic table, with nonmetals to its right and metals to its left.
What are some examples of carbon allotropes?
Except for lead, all of the carbon family elements exist as different forms or allotropes. Carbon, for example, occurs in diamond, graphite, fullerene, and amorphous carbon allotropes. Tin occurs as white tin, gray tin, and rhombic tin. Lead is only found as a dense blue-gray metal.
What is carbon used for?
Carbon is the basis for organic life. Its allotrope graphite is used in pencils and rockets. Living organisms, proteins, plastics, food, and organic building materials all contain carbon. Silicones, which are silicon compounds, are used to make lubricants and for vacuum pumps.
How many valence electrons are in a carbon atom?
Atoms of elements in this group have four valence electrons. The carbon family is also known as the carbon group, group 14, or the tetrels. Elements in this family are of key importance for semiconductor technology.
What are some examples of elements in a family?
Examples of element families are the nitrogen family, oxygen family, and carbon family.
Why does melting point decrease in carbon?
Melting and boiling points in the carbon family tend to decrease moving down the group, mainly because atomic forces within the larger molecules are not as strong. Lead, for example, has such a low melting point that it's easily liquefied by a flame. This makes it useful as a base for solder.
Why does the atom size increase as the group moves down?
Atom size increases moving down the group because an additional electron shell is added. Element density increases moving down the group. The carbon family consists of one nonmetal (carbon), two metalloids (silicon and germanium), and two metals (tin and lead). In other words, the elements gain metallicity moving down the group.
What is the first group of elements in the periodic table?
Group 1: Alkali metals group. Alkali metals group is the very first group (group 1) on the periodic table. The elements included in the Alkali metals group are; Lithium (Li)
Why are the elements in the bottom two rows of the periodic table included in group 3?
The elements in the two bottom rows of the periodic table are also included in these groups. They are placed in the two separate rows at the bottom because they show few different properties. Actually, the elements in the bottom rows are the extension of group 3 only. So they are included in group 3. But as these elements have few different ...
How many groups are there in the periodic table?
Groups are the vertical columns on the periodic table. There are total 18 vertical columns on periodic table. Hence there are 18 groups. The elements lying in the same groups show similar chemical properties and they also have same number of valence electrons.
What is the oxygen group on the periodic table?
Oxygen group is the group 16 on the periodic table.
What is an example of group 18?
Example of group 18. All the elements of group 18 are chemically inert (that means they do not easily react with other elements). And all the elements of group 18 have a complete octet (that means they have 8 electrons in their outer shell).
Which group is alkaline earth metals?
Alkaline earth metals are the group 2 elements on the periodic table.
