The Atomic Mass number does not equal the number of electrons in the element. The atomic number, on the other hand, does usually equal the number of electrons in the element, With the exception of ions.

∙ 12y agoNo. The number of protons plus the number of neutrons is the mass number.
The number of protons, which is also the number of electrons, gives the atomic number.

∙ 11y agono the atomic mass is the mass of the element. the atomic number tells you how many protons (and electrons when the atom is neutral)

∙ 11y agoHydrogen-1 is the only atom that has an atomic number which is similar to its mass number.

What happens to the total charge on a wire when a current flows through a wire?

How does electricity pass through lead?
The same as it does in any metal. Metals have a number of electrons that can move about freely; these carry the current.
Does aluminum cools faster than mild steel?
Yes, If if both samples are by equal volume of space not by mass, and heated at the same rate in the same time frame the answer is Yes.
How did the double helix structure match Chargaff's observations?
Chargaff observed that the number of Guanine units in a section/piece of DNA was the same as the number of Cysteine units and that the number of Thymine units equaled the number of Adenine units. This matched the double helix structure because Cysteine pairs with Guanine, and Thymine pairs with Adenine - meaning that Chargaff was right in that there must be an equal number of Cysteines and Guanines as well as equal Thymines and Adenines.
Why is the current in a series circuit the same all way round?
The number of electrons coming out of the positive end of the loop must be the same as the number of electrons going into the negative end. If it isn't, then electrons had to be created, or destroyed, or were injected, or leaked out, somewhere along the series loop.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
Is the mass number equal to the number of protons and electrons?
No, it isn't. The mass of an electron is significantly smaller than that of a proton.The mass of 1,800 electrons is about the same as the mass of one single proton.The antiparticle of the electron, the positron, has the same mass as the electron.the mass of the electron is not the same to the mass of the proton
A neutral atom of gold has a mass number of 197 and has 118 neutrons how many electrons does it have?
Any neutral atoms has the same number of electrons as protons, and any atom has a number of protons equal to the difference between its mass number and neutron number. Therefore, this atom has 197 - 118 = 79 electrons.
Which two particles in an atom are equal in a number?
Under normal conditions, i.e. non-ionic, the number of protons is equal to the number of electrons.
Do protons and electrons have the same number?
Yes, the atomic number is equal to the number of protons. The number of protons is also equal to the number of electrons
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
What has a equal number of protons and electrons?
An atom of an element.Not to be confused with an ion which can have more or less electrons than it has protons.an Atom.It means that it is a element because the atomic number in an element is the same as the number of electrons, and minused from the mass equals the number of neutrons. For example Oxygen has an atomic mass of 16 and an atomic number of 8 which means there are 8 protons 8 electrons (because they are the same) and 8 neutrons (they are just solid mass [16-8=8]).
How many electrons are in an atom of elemental sodium equal to?
The number of electrons in a neutral atom is equal to the atomic number; sodium has 11 electrons. The number of protons is the same.
Why do you calculate the number of electrons by the atomic mass and number?
because an atomic number is the same as the number of electrons in an atom (not ion)
What is equal to the number of protons which is equal to the number of electrons?
Do you mean what does the number of protons equal? This is the atomic number of the element. All isotopes of an element will have the same number of protons, only the number of neutrons varies.
Can the mass number be used to determine the number of electrons in an atom?
The number of electrons is the same as the number of protons, which is the atomic number of the element.
