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.
Yes, I believe two elements were added just a few months ago.
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.
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.
The Periodic table is a table with more than a hundred Elements on it. As of 2010, there are 118. Along with the names of the Elements there is the chemical symbol of the Element, the atomic number, and usually the atomic mass of the Element. The atomic number represents the number of Protons in one atom, and the atomic mass is the mass of the Protons and neutrons added together. The Electrons are not added onto the mass of the Protons and Neutrons because the Electrons are negligible.
The periodic table is added to in a way so that the element on the bottom row and furthest to the right is the newest discovered element. Making the most recent element added a nice fat go look it up.
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

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.

There are a number of elements that can be added to metals to increase their strength - carbon & tungsten are just two examples.
The elements needed for strong bones and teeth are Calcium, Magnesium, Phosphorous, and Fluoride. Milk is a good source of these elements.
The number of elements changes periodically because we as humans have the ability to create elements that do not exist in nature. As we create bigger and bigger ones, they are added onto the periodic table of elements.
