i don't know about 2
There are three elements in SnF2: one tin (Sn) atom and two fluorine (F) atoms.
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.
neutral
Helium has two valence electrons
there are 8 electrons in the valence shell of neon
One.
there are two elements, hydrogen and oxygen and one atom of each
Carbon monoxide (CO) is a diatomic molecule composed of one carbon atom and one oxygen atom, so it has a total of two elements.
There is one atom in Hydrogen and one atom in Chlorine. All elements are composed of only one atom.
Carbon monoxide is a molecule consisting of two elements: carbon and oxygen.
There is one element only. Oxygen atom is there.
You mean elements? So far scientists have brought out some 109 elements. If you mean atom model, then first Prout's model Then Thomson's, Rutherford's, Bohr's, Sommerfeld's. Finally vector atom model.
There are three elements in CO2: one carbon atom and two oxygen atoms.
Two elements, two hydrogen atoms and one oxygen atom
The number of neutrons will vary for every isotope of an atom and is not possible to generalize for all the elements.
there are 210 known isotopes in the element of sulfur i found this on sulfur factrs periodic table of the elements
No. Elements are make up of only one type of atom, rocks are made up of many different elements.
