Because it got the highest amount of protones.
The man-made elements will usually be found at the end of a modern periodic table. Look up periodic table in your search engine.
Elements at the extreme ends of the periodic table: high end - uranium, plutonium; low end - hydrogen (deuterium & tritium), lithium.
Krypton is found in the fourth period. Since in the periodic table its in the 4th row.
Because they do.
anions are negatively charged species anions are not seen on the Periodic Table. however the elements on the right end of the periodic table (except for noble gases, group 18) have a strong tendency to accept electrons are become anions
The two elements in the periodic table that end in "y" are beryllium (4) and mercury (80).
because they have completely filled orbitals
Helium is at the end of row 1 in the periodic table 1s2
There are 118 elements contemporarily found on the periodical table of elements. Some tables show Technetium, Radon, Neptunium, Plutonium, Americium, Curium, Berkelium, and Californium as naturally occuring elements. This is because some scientists claim to have found these elements in samples of Uranium. Honestly, I cannot inform you on how many there are, but I can tell you there are 29-20 man-made elements.
none of the elements end with u, just look at a periodic table
Nonmetals are located in the right corner of the periodic table of Mendeleev. See the link bellow for a periodic table. What? The nonmetals are located on the right of the periodic table, such as oxygen, nitrogen and chlorine.
Nitrogen is a nonmetallic element and is classified as a nonmetal in the periodic table.
