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)
Who developed your modern day periodic table?
The last major changes to the periodic table resulted from Glenn Seaborg's work in the middle of the 20th Century. Starting with his discovery of plutonium in 1940, he discovered all the transuranic elements from 94 to 102. He reconfigured the periodic table by placing the actinide series below the lanthanide series. In 1951, Seaborg was awarded theNobel Prize in chemistry for his work. Element 106 has been named seaborgium (Sg) in his honor.Although Dmitri Mendeleev is often considered the "father" of the periodic table, the work of many scientists contributed to its present form.
What are the three major categories the elements are broken down into in the Periodic Table?
The three major categories in the Periodic Table are metals, nonmetals, and metalloids. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are often dull in appearance and poor conductors of heat and electricity. Metalloids have properties that are intermediate between metals and nonmetals.
What is the major contribution of Dmitri Mendeleev to science and society?
Dmitri Mendeleev's major contribution was the development of the periodic table of elements. This organization of elements based on their atomic number and properties revolutionized chemistry and laid the foundation for modern chemistry and physics. His work has had a profound impact on scientific understanding and continues to influence research and education today.
What period address is oxygen in?

What major change occurs as you move from left to right on the periodic table?
More subatomic particles, more mass
What are the major groups of the periodic table?
it is poo symptom
Major region of the periodic table of the elements is?
it is metals
What are the names of the major categories in the periodic table?

When you move from left to right on the periodic table what are some of the major changes?
When you move from left to right on the periodic table, the atomic number of the elements increase.
What are the 2 major categories in the periodic table?
Metals and non metals
What is H called on the periodic table?
H on the periodic table represents Hydrogen. This is the lightest element but it is very essential to life because it is a major component to water (H2O).

What major change occurs as you move left to right on the periodic table?
As you move left to right on the periodic table, the number of valence electrons an element has increases. The number of valence electrons an element has corresponds to which group (column) an element is. (This rule does not apply to transition metals...)
What contributions to science were made by Dmitri Mendeleev?
He invented the periodic table. You must know what that means; he was the father of basic chemistry. Actually, he didn't discover the periodic table. He just arranged the only elements he had available in his day (not a lot) and arranged them based on patterns of # of protons, electrons, reactivity, etc. He didn't have an in-depth knowledge yet of electron configuration ;however, his "guess" turned out to have so many great implications that we now use his invention everyday everywhere.
Who two major families of elements does the bold staircase line in periodic table separate?
I am sorry but while you may see a bold staircase in the periodic table, this is not a universally recognized concept. We do not know what you are talking about and therefore can not answer your question.
