The atomic number, or Z, is the number of protons in the nucleus of an atom of an element. This is what determines what element an atom is. A link can be found below.
A sulfide ion has 16 protons and 18 electrons. The additional electron gives the ion a negative charge, making the number of electrons greater than the number of protons.
a negative ion means that an electron(s) has been gained. therefore, there will be a higher number of electrons than protons, as the number of protons will not change
subtract the number of protons from the number of electrons. The above answer does not answer the question!!
An atom typically consists of three main particles: protons, neutrons, and electrons. Protons and neutrons reside in the nucleus, while electrons orbit around the nucleus. The number of protons determines the atom's identity, while the total number of protons and neutrons in the nucleus gives the atom's mass number.
The atomic number correlates to the number of protons found in the nucleus of an atom. The atomic number also dictates the number of electrons that orbit the nucleus if the atom in neutral. Finally the atomic mass is the number of protons and neutrons found in the nucleus. The atomic number equals the number of protons (p+) or electron (e-).
This electron would have 51 protons and 51 electrons. The number of electrons in an atom is equal to the number of protons, as atoms are electrically neutral.
count the number of protons which will be equal to number of electron.
A sulfide ion has 16 protons and 18 electrons. The additional electron gives the ion a negative charge, making the number of electrons greater than the number of protons.
Is the number of protons or electron found in a given (neutral) element.
If an atom loses an electron, it becomes positively charged and is called a cation. This occurs because the number of positively charged protons in the nucleus is greater than the number of negatively charged electrons.
Atomic number = Number of protons = Number of electrons
The number of protons.
electron
Atomic number is the number of protons in the nucleus of an atom. Therefore, sodium's atomic number is always 11, even if it loses 1 electron. However, when a sodium atom loses 1 electron, it will form an ion with a 1+ charge.
The electron shell is the source of an element's chemical properties and the moderator of chemical reactions; the electron shell depends on the protons that constitute the atom
the answer is that it is called a atomic number.
mass number = protons + nuetrons
