It is, It is chemical index no.1
any of the elements who's existence we have proven is on the periodic table, if something isnt on the table it either hasn't been discovered, it isn't a pure element, or it doesn't exist
CO2 is not on the periodic table. The periodic table of elements, funnily enough houses all the elements. CO2 is a compound made up of other elements and therefore isnt on the table.
Da isnt an element on the periodic table. Sorry!
As you move down a group or family on the periodic table: The number of energy levels increases (true). The atomic radius increases (true). The number of valence electrons remains the same (not true - the number of valence electrons increases as you move down a group).
O is the chemical symbol but as oxygen readily combines into molecules it usually exists as O2 or as O3 (ozone)
the mass of electron is very less compared to that of a proton or a neutron it is 1/1800 the mass of 1 proton and therefore it is negligible and not included.

because t isnt in the periodic table. if it is in the periodic table then it only has one name. also it has more than one name because it is two solutions mixed together to make it

There are quite a few peninsulas in Africa. Included in the list are Horn of Africa, Ras Banas, and Shark Island.
1. When the Strong Nuclear force of an atom isnt strong enough to overcome the electromagnetic force of repulsion, the isotope is radioactive. 2.If the Element that you are analyzing has a number 84 and above on the periodic table, it automatically is too big to stabilize causing radioactivity. 3. If the element doesn't have the correct neutron/proton ratio, it can also be radioactive
Sorry no there isnt. Sorry no there isnt.
