A metal is normally viewed as cations in a sea of delocalised electrons. It is the metal atoms which donate their valence electrons to the sea of delocalised electrons.
NaCl is a molecule composed of two atoms Na and Cl.
Molecule
An atom for an ELEMENT and a molecule for a COMPOUND.
Butane is a compound and therefore is not present as an atom but as a molecule - which is more than one atom combined with another.
An element can be broken down to a single atom by physical means. A compound is made of 2 or more different atoms chemically bonded to another which cannot be broken down by physical means to a single atom. An example of a compound is water molecule and an example of an element is Iron.
O is an atom, but O2 is a molecule.
No, they are covalent bonds. An ionic bond is formed between a group 1 metal and Br.
An element, atom, crystal, compound, and molecule are all forms of matter.
O is an atom, but O2 is a molecule.
Its an element and an atom.
Is not a molecule or a atom it is a compound
An element is an atom or molecule made of a single type of atom. A compound is a molecule made of two or more different elements.
Carbon dioxide is a compound; therefore, its smallest unit is a molecule.
NaCl is a molecule composed of two atoms Na and Cl.
A molecule
neither a molecule or a compound
A molecule is the smallest part of a compound that still retains the properties of said compound. As the atom is the smallest particle of an element into which it can be divided and still retain all the properties of that element, the molecule is the atom's analog for a compound.
