The atomic number provides the total number of protons present in the nucleus. It gives the identity of the element. For a neutral atom, the number of proton and electron is the same and is equal to the atomic number. The letter Z denotes atomic number. ...
Ordinary atoms that either gain or lose electrons are called ions. If a neutral atom loses an electron, it becomes a positive ion. If it gains an electron, it becomes a negative ion. These basic subatomic particles—protons, neutrons, and electrons—are themselves made up of smaller ...
What is the term for the total number of protons and neutrons of the nucleus of an atom? If the number of in an atom is changed, it is no longer the same element. a) proton b) neutron c) electron An Al atom contains neutrons, protons, and electrons. An atom of sodium has an ato...
a)Identify the number of protons, neutrons and electrons for the following:1226Mg2+. (3marks) b)The mass number of an atom is16.It has8neutrons. What is the name of this atom? (1mark) c)Write the electron configu...
Because the mass of these nuclear particles is each approximately equal to one unified atomic mass unit (u), the sum of the protons plus neutrons is designated as the mass number ( A ). The mass of the electron is more than 1800 times smaller than the proton mass and, therefore, can ...
stability occurs when there is a largeenergy gapbetween a series of filled energy levels and the next level, which is empty. Such large gaps are said to separate shells, although these shells are not as clearly linked to thespatialstructure of the nucleus as electron shells are to their ...
Atoms are the basic unit of matter. Each atom has a dense nucleus composed of neutrons and protons. It also has a less dense outer electron cloud. Neutral atoms contain the same number of protons and electrons, which are positively and negatively charged, respectively....
A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives the number of electrons. Helium has 2 protons, so its atomic number is 2. Atoms are neutrally charged, so what links atomic number and the number of electrons? electron proton ...
While the number of protons remains the same in all atoms of an element, the number of neutrons can vary. Thus, atoms of the same element can have different mass numbers, and these are called isotopes. The weight of an electron is almost negligible. Thus, the atomic mass of an atom is...
