Why are two of the row of the periodic table separated from the rest of the chart?
They are called the Lanthanide Series and the Actinide Series. If you look carefully, you will see the the atomic #s (the little # on the top of each element) on the two rows are in between the atomic numbers in the main periodic table. Also, some versions of the periodic table have arrows showing where they are supposed to go.The two rows actually belong in the main periodic table. The first row belongs between elements 57-71, and the second belongs between elements 89-103.They are separated because if they were put in the main table, it would make it too long.Hope this helped!Read more: Why_are_two_row_of_the_periodic_table_elements_separated_from_the_rest_of_the_chart
Why cant the subscripts of a chemical equation be changed?
subscripts define the ratio of atoms to atoms, or ions to ions in a compound. they are set by the valence electrons, they only fit in certain ways. why change them other than to make balancing equations easier. balancing equations is not supposed to be too easy, just work harder at it. don't adjust the universe to fit into a simple way to look at things. NERD!
What is the closest metal to lawrencium?
In the periodic table before Lr is nobelium and after Lr is rutherfordium. Chemically, it is supposed that lawrencium is similar to lutetium.
Why is the periodic table set out the way it is today?
-to make room for new elements -to classify them in terms of their behavior -for easy recognition of elements -so the (period) and the (groups) would align The I2R company (probably best known for making lead donuts; or at least, that's what I mainly remember them for) used to publish calendars (okay, I lied: the calendars are what I mainly remember them for) with different styles of periodic tables. There was, for example, a circular (well, more of a spiral, with spikes) one, and one you were supposed to cut out and fold into a pyramid.
Do not taste chemicals without teacher's permission?

It is likely that an alien planet would lack these elements?
Generally is supposed that all the planets contain the same chemical elements. But, of course, it is necessary to analyse samples for the validation of this assertion.

Is ununpentium cation or anion?
Ununpentium is a provisional name for the artificial radioactive element with the atomic number 115. In the periodic table of Mendeleev Uup is situated in the group 15, period 7.The names of new chemical elements is regulated by IUPAC rules, seePure Appl. Chem., Vol. 74, No. 5, pp. 787--791, 2002.The word is composed from:un=1, un=1, pentium=5; derived from the Latin language.
