The answer depends on where you started from. The original table, as published by Mendeleev, had a number of gaps and new elements went towards plugging these gaps. However, after 1947, the new elements discovered were appended to the end of the table.
There are many relatively new elements that have been added to the periodic table over the last few decades, like the element Copernicium, a man made element that was discovered by the Gesellschaft fur Schwerionenforschung (GSI) in 1996. And although there have not been any discoveries in the last 14 years, there are quantum physicists that spend there time looking for the next element.
The periodic table is unlikely to change significantly in the next ten years as the fundamental properties of elements remain constant. However, new elements may be discovered and added to the table if they meet the criteria set by the International Union of Pure and Applied Chemistry (IUPAC).
Yes, I believe two elements were added just a few months ago.
including "unknown elements" there are 59 elements in half of the periodic table, not including them there is 55.5 Added: 92 natural elements/2 = 46 natural elements make up 1/2 periodic table.
Cobalt was officially discovered as an element and added to the periodic table in the late 18th century, with its discovery commonly attributed to the Swedish chemist Georg Brandt in 1735.
The system of the Periodic Table is not changed after the addition of a new element.

Four elements can be found. They are carbon.hydrogen,oxygen and nitrogen
As new elements were discovered and added to the periodic table, the elements were arranged based on their increasing atomic number and similar chemical properties. This resulted in new rows being added to accommodate the additional elements, expanding the table's size and complexity. The periodic table evolved to its current form with the addition of new elements and improvements in our understanding of atomic structure.
If the valence electrons are being added to the 4f orbitals, that means the element is lanthanides or actinides which further proves that the element is a heavy element and a member of f -block.

No elements if formed when carbon is added. When carbon , or any other element/metal is added , it is a mixture , known as an ALLOY. For various steels, the initial element is IRON, when carbon is added to form an alloy known as STEEL.

No, the whole idea of a stack is that elements can only be added at the top.
A priority queue is a collection of elements that each element has been assigned a priority and such that order in which elements are deleted and processed comes from the following riles: 1) An element of higher priority is processed before any element of lower priority. 2) Two element with the same priority are processed according to the order in which they were added to the queue.
