neutrons are found in the nucleus of the atom, while the electrons are outside the nucleus. The atomic number is the number of protons, while the mass number is the number of protons and neutrons. If an element is not charged, the number of electrons will equal the number of protons. ...
The sum of an atom's protons and neutrons is its What nuclide has 27 protons and 33 neutrons? The atomic mass is equal to: A. the number of neutrons. B. the number of protons plus the number of electrons. C. the number of protons plus the number of neutrons. D. the number of el...
What is the difference between atomic number and mass number of an atom? Parts of an Atom: Atoms are the smallest unit of an element that still retains its properties. Atoms are made of subatomic particles, protons, neutrons and electrons. The protons and neutrons are arranged in...
Normally, an atom of a given element has an equal number of protons and electrons. Protons are the heavy, positively charged particles found in the atom's inner nucleus, while electrons are light and negatively charged and orbit the nucleus. This means that there is no overall charge to the...
Every element has a unique atomic number. This is the number of protons in the nucleus of each atom. What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives the number of electrons. He...

In an electrically neutral atom, the atomic number (number of protons) is equal to the number of electrons. Why the Atomic Number Is Important The main reason the atomic number is important is because it's how you identify the element of an atom. Another big reason it matters is because ...

11、 charge) therefore, the # of protons = # electrons in an atom.slide 2.2atomic number determines the identity of the atom. it tells us the number of protons in the atom. it also tells us the number of electrons (b/c an atom is neutral in charge.) ex: atomic number of carbon,...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...
