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 elements that exist in nature as uncombined atoms called?
Elements that exist in nature as uncombined atoms are called native elements. Some examples include gold, silver, copper, and graphite. These elements are typically found in their pure form due to their stability and inert nature.
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 elements do not naturally occur as a diatomic molecules?
Some elements do not naturally occur as diatomic molecules, such as helium, neon, argon, krypton, and xenon. These elements exist as monatomic gases because they are stable in their single atom form due to having a full valence electron shell.
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 chemical elements have a subscript of two?
Some common chemical elements that can have a subscript of two in chemical formulas include oxygen (O2), hydrogen (H2), and nitrogen (N2). These elements can exist as diatomic molecules, meaning they naturally bond to form molecules composed of two atoms of the same element.
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.
What are elements that exist in nature as uncombined atoms called?
Elements that exist in nature as uncombined atoms are called native elements. Some examples include gold, silver, copper, and graphite. These elements are typically found in their pure form due to their stability and inert nature.

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.
Which items are related to compounds?
New physical properties are some of the items related to compounds.

Is it true that some elements are made up of only one element?
It's true that ALL elements are made up of only one element. Hydrogen contains ONLY hydrogen atoms. Not oxygen atoms, or silver atoms, or xenon atoms, or any other atoms. All known types of elements are listed in a periodic table. Compare elements to molecules. Elements are substances made up soley of one type of atom, which combine with other elements to form molecules. For example, water is written as H2O, 2 atoms of hydrogen and one atom of oygen - one molecule of water requires 2 different elements. Think of it this way, you can't breeak water down smaller than one molecule of water and have it still be water. Likewise, you can't break one atom of the element hydrogen down and have it still be hydrogen.
No elements exist as molecules?
No. Several nonmetals form molecules. Here they are with the molecules they can exist as. Some of the rarer molecules are excluded Hydrogen (H2), Carbon (C60 and other fullerenes) Nitrogen (N2), Oxygen (O2, O3), Fluorine (F2), Phosphorus (P4), Sulfur (S8), Chlorine (Cl2), Selenium (Se8), Bromine (Br2), Iodine (I2)
