If you mean do the exist as single atoms, no. Some can exist as molecules.
Hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine usually exist as the diatomic molecules H2, N2, O2, F2, Cl2, Br2, and I2 respectively. Oxygen can also exist as O3. Phosphorus can exist as P4 and arsenic as As4. Sulfur is usually found as S8. Carbon can exist as C60 and a variety of similar molecules.
An atom is a unit of matter that has all the properties of an element. It is the smallest unit of an element that retains the chemical properties of that element.
If you mean what kind of element can exist as one atom, the answer is the noble gases in group 18. All elements are composed of one kind of atom, having a unique number of protons, or atomic number.
A molecule of an element is a molecule made up of the same substance that can exist as an atom; for example, oxygen as O2.
Protons and neutrons exist in the nucleus of an atom. The electrons in an atom exist outside the nucleus. All elements have at least one proton; in fact the number of protons, which are positively charged, determines which element it is. Normally, all the elements except hydrogen (H) also contain neutrons, which have no charge (they're neutral, hence their name.)
An atom is an element. Every atom has a certain amount of protons, neutrons and electrons and these are what define which element that atom is.
The smallest unit of life that can exist as a separate entity is a cell.
It varies on the element of the atom.
The smallest unit of an element that is still that element is an atom. Some elements normally exist as molecules, but under some circumstances these can be broken down to individual atoms.
The smallest particle of an element that can exist is an atom. Atoms are made up of a nucleus containing protons and neutrons, surrounded by electrons.
An atom of that element has all the properties of that element.
It is an atom
The smallest particle of an element that can exist and still retain the properties of the element is an atom. Atoms are composed of a nucleus containing protons and neutrons, surrounded by electrons. The number of protons in the nucleus determines the element's identity.
An atom is a unit of matter that has all the properties of an element. It is the smallest unit of an element that retains the chemical properties of that element.
No, for all elements the smallest particle that can exist independently is an atom.
They are matterA molecule is the simplest complete structural unit of an element or compound that can exist in nature.An atom is the smallest component of any element having all the chemical properties of that specific element.
