What is unique about elements on the periodic table?
Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains.
What are the 7 chemical elements?
The elements of the periodic table sorted by atomic number
| Atomic number | Name chemical element | Symbol |
|---|---|---|
| 6 | Carbon | C |
| 7 | Nitrogen | N |
| 8 | Oxygen | O |
| 9 | Fluorine | F |
What are the elements arranged in periodic table?
The chemical elements are arranged in order of increasing atomic number. The horizontal rows are called periods and the vertical columns are called groups. Elements in the same group have similar chemical properties. This is because they have the same number of outer electrons and the same valency.
What are the first 40 elements?

What is the rarest element on the periodic table?
element astatine
A team of researchers using the ISOLDE nuclear-physics facility at CERN has measured for the first time the so-called electron affinity of the chemical element astatine, the rarest naturally occurring element on Earth.
What is the craziest element in the periodic table?
What is the craziest element in the periodic table?
- Caesium (element 55) Explodes in contact with water, in a much more dramatic fashion than its other alkali-metal brethren.
- Francium (element 87)
- Fluorine (element 9)
- Carbon (element 6)
- Osmium (element 76)
- Curium (element 96)
- Thallium (element 81)

What are the 4 ways elements are arranged on the periodic table?
Elements are arranged from left to right and top to bottom in order of increasing atomic number….The atomic numbers, temporary names and official names are:
- 113: ununtrium (Uut), nihonium (Nh)
- 115: ununpentium (Uup), moscovium (Mc)
- 117: ununseptium (Uus), tennessine (Ts)
- 118: ununoctium (Uuo), oganesson (Og)
Who arranged the periodic table?
chemist Dmitri Mendeleev
In 1869, Russian chemist Dmitri Mendeleev created the framework that became the modern periodic table, leaving gaps for elements that were yet to be discovered. While arranging the elements according to their atomic weight, if he found that they did not fit into the group he would rearrange them.
Are there atomic weights on the periodic table?
Atomic weights found within a periodic table one might think are constant. The truth is that atomic weights have changed as a function of time. Since 1899 the IUPAC Commission on Isotopic Abundances and Atomic Weights ( CIAAW) has been evaluating atomic weights and abundances.
When was the interactive periodic table of elements created?
Interactive Periodic Table of Elements The periodic table of the elements was first introduced in the mid-19th century by Dmitry Mendeleev. He organized the elements by atomic number, which is equal to the number of protons found in the nucleus of the element’s atoms.
Are there 94 elements on the periodic table?
The first 94 elements exist naturally, although some are found only in trace amounts and were synthesized in laboratories before being found in nature.Elements with atomic numbers from 95 to 118 have only been synthesized in laboratories or nuclear reactors.
