What are the elements that possess anions?
Only nonmetal elements can usually form monatomic anions, but some metallic elements, such as aluminum and iron, can form polyatomic anions that also include other very strongly electronegative elements, such as oxygen and fluorine.
Does neon exist in monoatomic gas at standard temperature and pressure?
No, neon exists as a monatomic gas at standard temperature and pressure. It does not readily form diatomic molecules or other larger clusters like some other elements.
What are the four most abundant elements in the human body What are some of the molecules they help form and why are these molecules important in terms of their biological functions?
The first four elements are oxygen, carbon, hydrogen and nitrogen.They form water, proteins, enzymes, etc.
Why is a monatomic compound nonsense?
A chemical compound always consists of two or more elements combined together, and therefore molecules of at least two atoms. A substance which was only one element would simply be a sample of the element. There are some monoatomic elements, the noble gases, helium and group 18 neon argon etc.
What are some elements with a single atom that cannot be combined?
When atoms combine to make molecules only the electrons adhere together to form bonds. The protons, neutrons, and nucleus do not combine.

what is called a molecule having one atom in it?
Monatomic compounds are composed of single atoms and there are no chemical bonds between these atoms. Diatomic compounds are composed of molecules containing two atoms. ... The main difference between monatomic and diatomic compounds is the number of atoms present in those compounds.
Can elements be molecules?
Yes, Molecules are what create elements. two oxygen molecules and one hydrogen molecule creates a water(element) Answer 2 An element consists of only one sort of atom, but in some elements these atoms join together to form molecules, but these molecules will only be made of one type of atom.

Can a molecule be an element?
Yes, some of the nonmetals (hydrogen, nitrogen, oxygen, and the halogens) form diatomic molecules (H2, N2, O2, etc.). Sulfur forms S8 molecules, phosphorus can form P4 molecules, and the ever versatile element carbon can form C60 molecules among others.
What makes carbon uniquely suited to begin the basis for biological molecules?
It is the ability of carbon to form strong, stable bonds to itself. This is called catenation. Some other elements can form bonds to themselves, but they are easily attacked by substances in the environment and the bonds are thus broken. Thus carbon can form the backbone of much bigger molecules than can other elements.
A molecule of a compound?
Most molecules are compounds but not all. Some molecules such as O2 and P4 are elements.
Are there any molecules or formulas for neon?
Under normal conditions of temperature and pressure, neon forms no elemental molecules. It can possibly form compounds with some other, extremely electronegative, elements. These compounds, if they exist, would have formulas.
What are elements composed of compounds atoms mixtures or molecules?
At sufficiently high temperatures and low pressures, all elements are composed of atoms. At standard temperature and pressure, some elements are composed of molecules, usually diatomic molecules, as with nitrogen, hydrogen, oxygen, and all the halogens.
What are some elements with a single atom that cannot be combined?
When atoms combine to make molecules only the electrons adhere together to form bonds. The protons, neutrons, and nucleus do not combine.
