you see how many electrons and protons it has and add them together
i don't know about 2
Yes. In a neutral atom, the +ve and -ve charges will be equal. Electrons are negatively charged, and protons have an equal and opposite positive charge. Therefore the proton number will equal the electron number. Elements are classified by their Atomic number, and this equals the proton number. So if you had a neutral atom with 6 elements, you know it has 6 protons in the nucleus and an atomic number of 6 - Carbon.
Number of protons in the atom.
The atomic number of an atom is the number of protons in the nucleus of that atom. The number of electrons will equal the number of protons in that atom if that atom is a neutral one. Other than that, we would have to know the atomic number (which is the number of protons that atom has), and the overall charge of the atom. With that information, we could discover how many electrons that atom had by simple mathematics. If an atom had 11 protons and a charge of +1, it would have one less electron than the number of protons, or 10 electrons. If an atom had 53 protons and a charge of -1, it would have 54 electrons. The ratio from atomic number to the number of protons in an atom is 1:1. The elements are categorized by the number of protons they have, as that is the difference between two elements. Conceptually, atomic number and proton number are the same.
Atomic number indicates the amount of protons present in the nucleus of an atom.
An element is a type of atom; on the periodic table of the elements, they are organized by atomic number (which is the number of protons in the nucleus of this atom).
We use atomic number for recognize chemical elements. atomic number means, how many protons are there in a single atom.
Your question is a little off, because atoms do not contain different elements; any given atom is an element, for example, a hydrogen atom, an oxygen atom, etc. An atom by definition is the smallest possible amount of a specific element. If you would like to know why atoms are a specific element, that is determined by the number of protons in the nucleus.
It is constant for elements. IT depends on number of protons that atom has.
Atomic number
It is about protons in a atom. We use it for idintify elements.
Elements are distinguished by their atomic number, which is the number of protons in the nucleus of an atom. The element's atomic number determines its chemical properties.
