Why is the periodic table so valuablee for chemists?
Periodic table group elements with similar properties together. It makes study of elements easier for chemists.
What class of element makes up the group on the right side of the periodic table?
non metals
I make up 78 of the air and am found in the 15th group of the periodic table?
Nitrogen makes 78% of the air. It also belongs to Group-15 of periodic table of elements.
Why iodine must appear in group 7 in the periodic table?
Iodine appears in group 7 of the periodic table (halogens) because it has 7 valence electrons. This property makes it chemically similar to other elements in the group, such as fluorine, chlorine, and bromine. Grouping elements with similar chemical properties helps in organizing the periodic table.
What elements from the periodic table make up earths metal?
Group-2 elements or alkaline earth metals(i.e.Be,Mg,Ca,Sr,Ba,Ra) makes up earth metals in periodic table
What Elements that makes the periodic table?
metals nonmetals
What makes a minerals?
Minerals are composed of elements. See a Periodic Table to learn more about the elements.
How many electrons will the elements have in the second group have on the periodic table?
Elements in the second group of the periodic table, also known as Group 2 or the alkaline earth metals, will have 2 electrons in their outer shell. This gives them a full s subshell and makes them relatively reactive.
What element group does not react with other elements?
Noble gases, group 18 on the periodic table, do not react readily with other elements due to their stable and full outer electron shells. This leads to low reactivity and makes them chemically inert.
What is the most reactive group of elements?
It is in Group 17 that you will find the most reactive elements. These elements all lack only one electron from having that "magic" electron configuration of the inert gases. That makes these elements very "hungry" to get that "last electron" so their electron structures become more stable.
Is science almost done with the periodic table?
Science is dependent on periodic table. It makes the study of elements easier.
How are elements catagorized in the periodic table?
The periodic table is organized in rows and colums called periods and groups. each period in the table helps correspond to the filling of a configuration of the outermost electron shells of their atoms.
