What atomic number always equal to the total number of?
Electrons or Protons. As they are effectively equal in no in a neutral atom.
How many protons in an uncharged atom?
equals the total number of electrons in the orbital shells.
Should you use atomic number or atomic mass number for electronic configuration?
Atomic number. This gives the count of protons in the nucleus and therefore the posiitive charge of the nucleus. For an uncharged atom it therefore gives the total number of electrons in all shells
What is the differnece between mass number and atomic number?
Answer 1The mass number of a nuclide is the sum of the mass of the protons and neutrons in the nucleus. Protons and Neutrons have a mass of approximately 1 atomic mass unit (electrons are not included since the mass relative to the mass of a proton and neutron is to small to count in the total mass. The atomic number of an atom corresponds to the number of protons in the nucleus, and that is the difference.Answer 2Mass number is the total number of protons and neutrons in the nucleus of an isotope. Atomic number is the total number of protons in the nucleus of each atom of an element.
What is The atomic number of an element is the total number of which particles in a nucleus?
The atomic number is equivalent to the number of protons or electrons (in the neutral state of an atom).
How many electrons are in a selenium ion?
Selenium has 34 total electrons. It has 6 valence electrons.
Difference between Na and Na plus?
Na+ will be a sodium atom that has lost an electron. Normally in atoms the amount of protons and electrons are equal, when you see a plus or minus charge on an atom its due to the loss or gain of electrons.
How is the atomic number related to the core electrons?
the number of valence electrons plus core electrons is the atomic number
What is the difference between the atomic number and mass of an element?
Atomic number is the number of protons in the nucleus of the atom. But Atomic Mass is the mass of the nucleus and mass of the electrons around the nucleus. If suppose we say the mass number then it is the total number of protons and neutrons in the nucleus. Nucleon is the common name for both proton and neutron. Hence mass number is the total number of nucleons.

6 The atomic number of oxygen is 8 because oxygen has?
The atomic number of oxygen is 8 because oxygen has 8 protons in its nucleus.The atomic number of a chemical element (also known as its proton number) is always the number of protons found in the nucleus of an atom of that element, and identical to the charge number of the nucleus. It is conventionally represented by the symbol Z.The Atomic Number is a count of how many Protons are present in an atom of an element.The element Oxygen has 8 Protons in its atomic nucleus and therefore has an Atomic Number of 8.Note: in an electrically neutral atom the number of electrons in the electron cloud exactly matches the number of Protons in the nucleus of the atom, therefore electrically neutral oxygen will also have 8 electrons.
What is total charge of an atom?
Short Answer:The total charge of an atom is the number of protons in the nucleus, minus the number of electrons around the nucleus. Normally, atoms have as many protons as electrons and the atom is neutral, otherwise, it is a negative ion with a charge of -1, -2, etc if it has extra electrons or +1, +2 etc if it is missing electrons and is a positive ion.Explanation:Atoms have a positively charged nucleus and a collection of negatively charged electrons around the nucleus. Because each proton in the nucleus has a positive charge of exactly the same size as the negative charge of an electron, when the normal atom has as many electrons as protons, the total charge of the atom is zero. It is a neutral atom.If there is one more electron than than the number of protons, there is a net negative charge of -1. If the atom is missing an electron, the total charge is +1.If an atom has one or more extra electrons, we say it is a negative ion and the total charge of the ion is -1 or -2 or "-" the number of extra electrons.If an atom is one or more electrons, we say it is a positive ion and the total charge of the ion is +1 or +2 or "+" the number of missing electrons, i.e. the excess number of protons.Total Charge = (number of protons) - (number of electrons).
What is the difference between the atomic number and atomic mass of an element?
Atomic number is the number of protons in the nucleus of the atom. But atomic mass is the mass of the nucleus and mass of the electrons around the nucleus. If suppose we say the mass number then it is the total number of protons and neutrons in the nucleus. Nucleon is the common name for both proton and neutron. Hence mass number is the total number of nucleons.
How many electrons orbit the nucleus of a lead atom?
A total of 82 electrons
1 In an electrically neutral atom the number of protons in the nucleus is equal to the number of?
In an atom, the number of electrons is equal to the number of protons in the nucleus of the atom. This only varies in ions, where electrons have been added to an atom or removed to create a full outer shell.
What atomic number always equal to the total number of?
Electrons or Protons. As they are effectively equal in no in a neutral atom.
The atomic number of an atom indicates the number of?
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
