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.
What is the symbol for an ion with 16 protons 16 neutrons and 18 electrons?
S for sulfur because the number of protons tells you the atomic number with is 16 and 16 is sulfur. The electrons means it is an ion with two more electrons than protons. The neutrons have no charge but add mass to the element.
How many protons electrons and neutrons in a sulfide ion?
Sulpher atom has an atomic no. of 16 and a mass no. of 32 neutrons = mass no. - atomic no. = 32 - 16 = 16 when an atom becomes an ion only theelectron no. changes while the proton and neutron no. stays the same. the neutron no. changes in isotopes only!!!
What is the symbol for sodium with 11 protons and 10 electrons?
The symbol for sodium with 11 protons and 10 electrons is Na+. The plus sign indicates that the sodium atom has lost one electron, resulting in a positive charge.
What indicates the number of an electron in a neutral atom?
The number of an electron in a neutral atom is indicated by the atomic number, which is equal to the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is the same as the number of protons.
What is the number of protons and electrons in a sulfide ion -2?
A sulfide ion has 16 protons and 18 electrons. The -2 charge indicates that the ion has gained two electrons, giving it two more electrons than protons.
Indicates the number of protons and electrons for this Sulfide ion?
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.
Select the answer that correctly indicates the number of protons and electrons for this atom or ion CL-1?
The atom chlorine usually has 17 protons and 17 electrons. However, the ion Cl-1 indicates that it has gained one electron, so it now has 17 protons and 18 electrons.
How many electron and protons does Sulfide ion have?
16 protons and 18 electrons
A sulfide ion S2- has how many protons?
A sulfide ion (S2-) has 16 protons. This is because the sulfide ion carries a charge of -2, indicating that it has gained two extra electrons, and thus has 16 protons in its nucleus as the number of protons always determines the element.
What is true of sulfide ion?
it has 2 more electrons than protons.
What does a charge on a ion indicate about the number of protons and electrons?
The charge on an ion indicates the imbalance between the number of protons and electrons. If an ion has a positive charge, it has more protons than electrons. If it has a negative charge, it has more electrons than protons.
What does atomic numbers indicate?
It indicates the protons. Periodic table is based on atomic number.
What is the chemical formula for sulfides?
sulfide=sulfur+2 electrons(to fill the outermost energy level) sulfur=16 protons-16 electrons=0 (which is newtrons) sulfide=16 protons-18 electrons(by adding 2 electrons to fill the outermost energy level) =-2
How many protons and neutrons and electrons has helium got?
Helium has 2 protons, 2 neutrons, and 2 electrons. The atomic number of helium is 2, which indicates it has 2 protons and 2 electrons in a neutral atom.
How many electrons does sulfide ion have?
A Sulfide ion has a full complement of 8 valence electrons. Sulfur is element 16. It has 6 valence electrons in its outer energy level, however, sufide is S2- so it has gained 2 electrons to fill its outer energy level.
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.
