What are the 8 elements of nature?
The elements: Fire, Water, Earth, Air, Nature, Ice, Light, Darkness..
What are the free elements?
In chemistry, a free element is a chemical element that is not combined with or chemically bonded to other elements. Examples of elements which can occur as free elements include the oxygen molecule (O2) and carbon. All atoms of free elements have an oxidation number of 0.
What is the most powerful element?
FireFire — The most powerful element. Nothing can exist before the most brilliant flames. Fire is the symbol of the beginning and the end, the light source, and the soul.
Why are actinides Coloured?
Actinide cations are coloured? … The colour is due to electronic transition within the 5f levels. The electronic transitions of actinides are about ten times more intense than those of lanthanides. The difference is due to difference in 4f and 5f electrons.
Which element is never found free in nature?
Alkali metals are the first group in the periodic table. They are never found in nature uncombined because they are unstable and they react fast to other elements. They bond well with all elements except the noble gases.

What was the first man made element?
technetiumThe name is from the Greek word for artificial, since technetium was the very first man-made element, yet despite the name, technetium is found naturally albeit in tiny traces.
Why are all actinides radioactive?
The radioactivity of the actinide elements is caused by their nuclear instability. In order to become more stable, the nucleus of an actinide element undergoes radioactive decay, releasing gamma rays, alpha particles, beta particles, or neutrons.
Is it possible that there are unknown elements?
Although there are elements we have not yet created or found in nature, scientists already know what they will be and can predict their properties. For example, element 125 has not been observed, but when it is, it will appear in a new row of the periodic table as a transition metal.
Are there really 98 naturally occurring elements?
Of the 118 elements that have been discovered, there are 90 elements that occur in nature in appreciable amounts. … So, the grand total of natural elements is 94 or 98. As new decay schemes are discovered, it’s likely the number of natural elements will grow.
Are actinides rare?
Within the actinides, there are two overlapping groups: transuranium elements, which follow uranium in the periodic table; and transplutonium elements, which follow plutonium. Compared to the lanthanides, which (except for promethium) are found in nature in appreciable quantities, most actinides are rare.
What is the rarest element?
element astatineA 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.
Is it possible that there are more elements?
The only elements left to discover fall into the super-heavy category — elements that contain more than 104 protons — says Dr Elizabeth Williams, a nuclear physicist at the Australian National University. But it is unlikely we will discover any new naturally occurring super-heavy elements on Earth, says Williams.
What elements Cannot be found in nature?
Six of these occur in extreme trace quantities: technetium, atomic number 43; promethium, number 61; astatine, number 85; francium, number 87; neptunium, number 93; and plutonium, number 94.
What is free state in nature?
The metals that can be found in the free state in nature are gold, silver, platinum,e etc. Since Gold, Platinum and Silver are least reactive metals, hence they are found in free state in nature.
What is not a native element?
The noble gases include helium, neon, argon, krypton, xenon, and radon. Similarly, diatomic gases, such as hydrogen, oxygen, and nitrogen are not considered native elements.
Can elements be man made?
A synthetic element is one of 24 chemical elements that do not occur naturally on Earth: they have been created by human manipulation of fundamental particles in a nuclear reactor, a particle accelerator, or the explosion of an atomic bomb; thus, they are called “synthetic”, “artificial”, or “man-made”.
What are the 7 elements of earth?
Most actions and effects achieved through the use of magic can be divided and categorized into one Elemental dominion, which indicates the region of influence. The seven Elements are Nature, Water, Fire, Earth, Light, Darkness, and Spirit.
Can there be new elements?
We most definitely will! New elements are created by smashing known ones together at super-fast speeds. … The labParticoratories that found ununoctium (and other elements) are already busy smashing more atoms together in the search for elements to start a new row of the periodic table.
Are actinides man-made?
Actinides are the 15 elements with atomic numbers from 89 to 103. They are named after the first element in the series, actinium. The actinides group includes mostly man-made elements with only a few exceptions such as uranium and thorium.
