The electrons in the outermost shell
An atom of an element is comprised of protons, electrons, and usually neutrons. The specific element is determined by the number of protons, and so there is only one particle that determines the element.
The number of protons determines the element's atomic number. When combined with the number of neutrons, it determines the element's atomic mass.
No that is not true. The number of PROTONS determines what the element is.
DNA determines a specific trait.
No. The element's atomic number determines how it forms compounds.
The number of protons (aka atomic number) determines the element or substance.
There are specific factors that can contribute to a the properties of chemical elements. Some of these factors include the amount of valance electrons in the element.
An element is the type of substance it is, for example, oxygen, hydrogen, etc. An atom is the combined particle consisting of electrons spinning around a nucleus, which is made up of protons and neutrons. The number of protons in an atom, not element, determines the type of element it is. If the atom looses a proton, then the element changes to a different one.
The number of protons.
protons
the number of atoms is 19 an 20
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
