Which three groups of the periodic table contain the most elements classified as metalloids?
The three groups of the periodic table that contain the most elements classified as metalloids are: Group 14 (Carbon group), Group 15 (Nitrogen group), and Group 16 (Oxygen group). These groups have elements such as silicon, germanium, arsenic, antimony, tellurium, and polonium that exhibit properties of both metals and nonmetals.
What were the three missing elements in mendeleyev chart?
The missing elements that Mendeleev predicted in his periodic table were germanium, gallium, and scandium. Mendeleev left gaps in the table for these elements based on the patterns he observed in the known elements at the time.
What are the three transition element groups?
The transition elements are typically divided into three groups: the first transition series, the second transition series, and the third transition series. These groups are based on the position of the elements in the periodic table.
Name the 3 major groups on the periodic table in order of their decreasing sizeWhere on the periodic table is each group located?
The 3 major groups are: # Metals - Groups 1-15 and the Inner Transitional Elements # Nonmetals - Groups 1 and 14-18 # Metalloids - Groups 13-17 (Diagonal strip of elements separating the metals from the nonmetals)
What are the elements in groups 3 through 12 called on the periodic table of elements?
The elements in groups 3 through 12 on the periodic table are known as transition metals. These elements are characterized by their ability to form stable ions with partially filled d orbitals. They often exhibit multiple oxidation states and are known for their catalytic properties.
What are the three lightest elements in the periodic table?

What are the three main classes of elements in a periodic table?
Three main classes are:MetalsNon metalsTransition elementsThey are present in periodic table.
What are the three element groups called?
Periodic table has 18 groups; see the link below.
Are more than three-fourths of the elements in the periodic table non-metals?
No it is the other way around. The majority of elements in the periodic table are metals.
Who Organized elements into four groups based on properties?
In the early 19th century, the chemist Johann Wolfgang Döbereiner organized elements into groups of three, known as triads, based on their similar chemical properties. This classification laid the groundwork for later developments in the periodic table. However, it was Dmitri Mendeleev who is most famously credited with organizing elements into a more comprehensive periodic table in 1869, grouping them by their atomic mass and properties.
Are most elements on the periodic table nonmetals?
No, more than three-fourths of the elements are metals. Love, Grahamcracker
What are the names of three metalliods from the periodic table of the elements?
Si, As and Te
