Changing the number of protons in the nucleus of an atom changes it to another atom (for example hydrogen becomes helium)
Changing the numer of electron at the same rate as the increase in protons occurs as the atom becomes another species of atom (see previus case)
Changing the number of neurons in the nucleus of the atom while leaving the number of protons constant changes the atom to an isotope of the original atom (same name)
Changing the just the number of electrons in the atom while leaving the proton number as is changes the atom to an ion, but it retains essentially the same name (chlorine becomes the chloride ion)
Atoms with a different number of neutrons (neutral particles) are called isotopes.
An Isotope. Isotopes are one of two or more atoms having the same atomic number but different mass numbers (i.e. different no of neutrons).
ions, with a loss of electrons it would be called a cation and with a gain it would be called an anion
an ion
Atomic numbers are the number of protons and electrons in a atom.
Always the Atomic Number = Number of Protons If electrically neutral, Atomic Number = Number of Electrons = Number of Protons
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.
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.
The number of electrons can be determined if the overall charge and number of protons are known. If the charge of an atom is neutral, then how ever many protons it has it will also have that number of electrons.
The number of protons is a specific characteristic of an atom; if the number of protons is other the element is other.
A neutral atom of a chemical element has a constant number of protons and electrons; loss or gain of electrons transform this atom in an ion.After the change of the number of protons the identity of the atom is lost.
The number of electrons should equal the number of protons, otherwise you have an ion.
protons and electrons are identical in number in an atom
The number of electrons should = the number of protons.
protons, because the protons are positive and the electrons are negative so to have a neutral atom the protons and electrons must be balanced
An ion
In a neutral atom the number of electrons is equal to the number of protons; and the number of protons is the label of a chemical element.
Because it hs a different number of protons and electrons
The number of protons in an atom is equal to its atomic number. In a neutral atom, the number of electrons is equal to that of protons. If the atom is negatively charged, add it to the number of electrons; and if positive, subtract.
No. The number of protons and electrons is the same, resulting in a neutral atom (magnesium in this case). In order to be an ion the number of protons and electrons must be different.
The name is ion.
