Element
The atomic number is defined as the number of protons in an atom. The number of electrons will always be the same if the atom is neutral- if the atom is not neutral we usually call it an ion. The number of neutrons can vary, and make what are called isotopes. For example, carbon has atomic number 6, meaning every carbon atom has 6 protons. Every neutral carbon atom has 6 electrons. Carbon can have several isotopes, the most common of which is carbon-12 and carbon-14. Carbon 12 has 6 protons and 6 neutrons, and carbon 14 has 6 protons and 8 neutrons. Answer: atomic no. of an element= no. of protons = no. of electrons while no. of neutrons = mass no. - no. of protons
The number of protons in an atom of an element is its atomic number. It determines the element's identity and is unique for each element. The number of protons also defines the element's chemical properties.
The number of protons in the nucleus of an atom determines its identity as a particular element. The number of protons is the element's atomic number, and is unique to each element. For example, the atomic number of oxygen is 8, while the atomic number of carbon is 6.
No because the number of protons never changes or else the element changes.
Element
Each carbon atom (atom number 6) has 6 protons (in nucleus) and 6 electrons (orbited around), the number of neutrons (also in nucleus) may vary from 6 or (less common) 7 or (rarely) 8.
The mass number of a carbon atom is 12. This number represents the total number of protons and neutrons in the nucleus of the carbon atom.

Every element can have different mass numbers; these reflect the number of neutrons in the atom in addition to the protons that determine which element it is.
Every element has its own kind of atom, identifiable from atoms of another element by its number of protons.
Yes. It is true. An atom with a different atomic number is an atom of a different element.
The atomic number of an element is the number of protons in the nuclei of its atoms. Each element has a unique atomic number.
Yes that is true Every atom of a given element does have the same number of protons.
The atomic number is the number of protons in an atom. In an electrostatically neutral atom, ie not an ion, it is also the number of electrons. Every single atom of an element will have the same number of protons, eg. Carbon always has six protons. This also helps us to understand the layout of the electron in an atom. Carbon has six so it arranges them into an inner group of two and an outer group of four, meaning it can have up to four bonds. Hope this helps.
Carbon is an element
You mean the smallest particle of an element that still retains that element's properties. It is the atom. Even one atom of, say, carbon is still carbon. Cut it up any further and you no longer have carbon.
