Is this statement true or false The periodic table of the elements is now complete because there are no more elements to add.?
False. The Periodic Table is not complete as new elements are still being discovered or synthesized by scientists. These elements are typically new, man-made elements that are highly unstable and exist only for a very short time.
What else can I help you with?
Which are more common metals or nonmetals?
Metals are more common than nonmetals. The majority of elements on the periodic table are metals, and they are found in various forms in nature. Nonmetals are less abundant and typically found in combination with other elements in compounds.
The table is called the periodic table because?
Because in the table the elements are arranged into "periods", elements belonging to the same period have similar physical/chemical properties. This in tern reflects the fact that they have a similar number of outer shell electrons.
Which statement best explains why the elements in groups 13 to 18 of the periodic table are called p-block elements?
These elements are called p-block elements because their outermost electrons are in the p orbital. In the groups 13 to 18, the electrons fill the p sublevel in the outermost energy level of the atom, which gives these elements their unique properties.
He is called the ''Father of the periodic table'' his periodic table organized the elements according to increasing what?
He is called the "Father of the periodic table" because he organized the elements according to increasing atomic mass.
Why is the periodic table periodic?
The periodic table is periodic because elements are arranged in order of increasing atomic number, which results in similar chemical properties repeating at regular intervals.
Why is the alien periodic table not complete?
The alien periodic table is a hypothetical concept based on the idea that elements could exist in unknown parts of the universe with different properties from those we know on Earth. It is not complete because our understanding of the universe is limited, and we have not discovered all possible elements or their properties.
Why its called periodic table?
Because the elements progress in a periodic function.
The periodic table is called periodic because the?

Why is the mendeleevs table called the periodic table?
Because the properties of the elements change in a periodic fashion. In the early versions, when fewer elements were known, the chemically similar elements were thought to occur every eight positions.

What complete family of chemical did mendeleev leave out of his periodic table?
Mendeleev left out the noble gases (Group 18) from his periodic table because they were not discovered yet at the time he developed the table. These elements were later added to the periodic table as they were discovered.
Why are there only 10 elements in the d block on the periodic table?
because thats how the periodic table is
Are there only 90 different elements?
no because there are 92 elements in periodic table that are natrul
