Why is aluminum not found as a free element?
Aluminium is found not in a free state because it is so reactive that it reacts with oxygen.
Which two elements occur in a nature as liquid?
Only mercury is a chemical element which occur in the nature as a liquid.
Do hydrogen nitrogen and oxygen normally occur as single atoms?
With the conditions of temperature and pressure found on the Earth hydrogen and oxygen in their free state are gas molecules consisting of two atoms. But nitrogen gas can also be found in this form.
What is usually defined as the state of being concealed or free from unauthorized intrusion?
Privacy
Why molten copper chloride conduct electricity?
As copper and chlorine are bonded by ionic bonding , they are placed in a crystal lattice and there is no free moving ions to conduct electricity at the solid state. In molten state, the ions are free to move about.
Why most elements not found in the free state in nature?
Most elements are sufficiently reactive so it can not exist in elemental form.
Does copper occur in free state?
Yes. copper is one of the elements that may, with luck, be found in the native state.
A widely distributed nonmetal which is never found in its free elemental state?
There are many nonmetals that are rarely found in their elemental form naturally. One of the more widespread of these is chlorine. Because chlorine is so reactive, it is almost always present as compounds, such as sodium chloride.
Is chlorine found in its elemental state or combined with other elements?
Chlorine is never found free in nature. It is always combined with another or other elements into compounds. Chlorine is highly reactive, and it wants to borrow an electron from just anything it can get close to. In general, it actually wants to "steal" that electron to form an ionic bond, and sodium chloride (NaCl), which is table salt, is one example of a common chlorine compound.
What element is a widely distributed nonmetal never found in its free elemental state and is an essential component in all cell protoplasm DNA and various animal tissues and bones?
carbon
Which of these is not an ore copper carbon silver iron?
copper, silver and carbon are not real ores but could be found as pure elements: carbon as coal, or diamond. Silver as nuggets. Copper as native copper specimen. Iron is almost never found in the free elemental state, and should be extracted from iron ore, which is not iron, but mainly made of iron oxides.
Why are most element not found in free state in nature?
most elements have partly filled orbitals (or shells) and they try to gain, lose or share electrons so as to satisfy octet rule. Hence they are reactive and not generally found in free state
Why is all compounds molecules?
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.
Is all molecules compound?
All elements and compounds are present in molecular state. They cannot be found as individual atoms. Atoms cannot exist in free state.
Which of the following groups in the periodic table contain elements so reactive that they are never found in the free state?
group 1 and 2
What are the free elements in earth's crust?
Approximately 100 free elements are found in the earth's crust. There are eight elements that are found in somewhat of an abundance. These include: oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium.
What groups of elements is most likely to contain elements that will be found free in nature?
The noble gases.
