Why aren't there many more than 100 occurring elements?
Because scientists just simply add a proton to an element, and they get the next element. For example, of you had one sodium atom (all sodium atoms have an atomic number of 11), and added a proton to it, you would get magnesium atom (all magnesium atoms have an atomic number of 12). So if scientists did this with element 99, they get element 100.
What are the 10 elements with atomic number?
all element have an atomic number.
What is used to find the atomic number of an element?
The atomic number of an element is the number of protons in the nucleus of its atom. It is typically found on the periodic table of elements, where elements are arranged in order of increasing atomic number. Each element has a unique atomic number that distinguishes it from other elements.
How will the modern periodic table be disturbed if isotopes of an element are discovered now?
The periodic table would be disturbed only if isotopes of a new element are discovered, because a periodic table is based on order of atomic number, not atomic mass. If new isotopes of a previously known element were discovered, the atomic mass shown in the periodic table might be changed, but this is very unlikely because the atomic masses shown in a periodic table are based on the naturally occurring distribution of isotopes, and any newly discovered isotopes would probably occur only in very small fractions of the total.
What does atomic mass number elements symbol elements name and atomic mass tell you about the element?
The element symbol represents one mole of element , atomic number represents number of protons, atomic mass represents sum of protons and neutrons.
What two elements in the periodic table have many same properties?
because all the element are not discoverd and those are discovered that are have same atomic no.
What was the last element discovered?
Francium (Atomic Number 87), the Last Discovered Natural Element
What describes an atomic number of an element?
The atomic number of an element is the number of protons in the nucleus of an atom of that element. It determines the unique identity of an element and its position on the periodic table. Elements with the same atomic number belong to the same element, while elements with different atomic numbers are different elements.

What element has a smaller atomic mass than element 5?
If "element 5" in this question means the element with atomic number 5, then all of the elements with atomic numbers 1 through 4 have smaller atomic masses. These elements are hydrogen, helium, lithium, and beryllium.
What elements combined atomic number gives 12?
An atomic number goes with a single element notto a combination of elements.
What element has 125 atomic number?
The element with atomic number 125 is unknown, as it has not been discovered or named yet. Elements beyond uranium (atomic number 92) are typically synthesized in laboratories and have very short half-lives.
Which element has an atomic weight?
All elements have an (atomic) weight or mass.
What are the 10 elements with atomic number?
all element have an atomic number.

What canot be a proper symbol for an element?
The elements that are newly discovered or are radioactive and found in traces are usually named according to a system of nomenclature based on their atomic nos.Eg. element 243 (if discovered, some day) will be named as biquadtrium (Bqt) which is NOT the proper symbol/name for the element.
