Why are two of the rows of the periodic table deprecated from the rest of the chart?
There are two rows deprecated from periodic table because they have different properties.They are referred as lanthanides and actinides
Which of the following is an extreamly reactive family of elements?
Sodium, Potassium, and the rest vertically below it on Periodic Table.
Are there more nonmetals than metals on the periodic table?
Yes. There are only about 20 nonmetals and only 7 metalloids. The rest of the elements are metals.
What is element 120 on the periodic table?
There is no element 120. The highest atomic number according to the current periodic table is 118, of which only 3 atoms have been synthesized. There are only 92 naturally occurring elements. The rest have been, or will be synthesized in special laboratories.
Which two elements on the periodic table have alternative spellings in Europe?
In England, cesium is spelled caesium, and aluminum is spelled aluminium. I don't know about the rest of Europe.
Where is lanthanides and actinides in the periodic table?
The 2 bottom rows separated from the rest
How does the reactivity of the atoms in the periodic table change as you go from top to bottom?
As I understand it scientists took an educated guess at the Hydrogen Atom and all the rest were extrapolated from there.

Each row in the periodic table ends when an outer energy level is what?
filled. That would be 2 electrons for helium, and 8 electrons for the rest of the noble gases in group 18 on the periodic table.

Sodium, Potassium, and the rest vertically below it on Periodic Table.

Is radon a metal or a nonmetal?
Radon is an inert or noble gas, and that's as far from being a metal as an element can get. You'll find radon at the bottom of the Group 18 elements (naturally) on the periodic table. Use the link below for more information.
Which nutrients are also known as elements?
Calcium and Iron are 2. On the periodic table, look for the rest around these 2
What is the order in the modern periodic table?
Rows by Engery Rings supposedly, Columns by oxidation number, and the rest by atomic number.
What language is most used on the periodic table?
Primarily Greek, about 64 the rest are German, Spanish, Latin, and Americanized Latin.
What are the least common elements on the periodic table?
the ones at the very bottom two rows (langthanides and actinides), which are separated from the rest of the table. Some of these are "man made" so to speak, and others are known to exist in theory, but have not been discovered. They are very reactive, often radioactive and do not usually exist as pure substances in the environment.
What is element 120 on the periodic table?
There is no element 120. The highest atomic number according to the current periodic table is 118, of which only 3 atoms have been synthesized. There are only 92 naturally occurring elements. The rest have been, or will be synthesized in special laboratories.
