How many electrons does S2- have if sulfur has an atomic number of 16?
A sulfide ion, S2-, has 18 electrons. A neutral sulfur atom has 16 electrons, the same as the number of protons, which is the atomic number. Since electrons have a negative charge, a sulfur atom must gain two extra electrons in order to form the sulfide ion with a charge of 2-.
In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
How do you calculate the number of protons neutrons and electrons of an atom?
The charge of an ion can be calculated by adding up the protons and subtracting the electrons. When oxygen with 8 protons has 8 electrons it is neutral, when it has 7 electrons it is positively charged.
Is an atom with 12 protons 12 electrons and 12 neutrons an ion?
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.
What is an atom called when the number of protons is not equal to the number of electrons?
An ion. If there are less electrons than protons, the atom gains a positive charge and is called a cation. If there are more electrons than protons, the atom gains a negative charge and is called an anion.
Select the answer that correctly indicates the number of protons and electrons for this atom or ion Sulfide ion?
16 protons and 18 electrons
Indicates the number of protons and electrons for this Sulfide ion?
16 protons and 18 electron
A sulfide ion S2- has how many protons?
The number of protons of an element does not change when it undergoes a chemical change. It is the number of electrons that changes. Sulfur has 16 protons, and so does the sulfide ion. However, sulfur has 16 electrons, while the sulfide ion (S2-) has 18 electrons.
How many electron and protons does Sulfide ion have?
16 protons and 18 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.
What is true of sulfide ion?
it has 2 more electrons than protons.
How many electrons does S2- have if sulfur has an atomic number of 16?
A sulfide ion, S2-, has 18 electrons. A neutral sulfur atom has 16 electrons, the same as the number of protons, which is the atomic number. Since electrons have a negative charge, a sulfur atom must gain two extra electrons in order to form the sulfide ion with a charge of 2-.
What is the number of protons and electrons for Lithium ion?
Lithium ion is Li^1+ and the number of protons is 3 and the number of electrons is 2.
Does a chloride ion have equal protons and electrons?
No. By definition an ion is electrically charged and so must have a different number of protons and electrons. A chloride ion has 17 protons and 18 electrons.
What do you call unequal number of protons and electrons?
All atoms have the same number of protons and electrons, but an atom with a different number of protons and neutrons is called and isotope
Is an ion with 8 protons and 10 electrons positively charged?
Protons are positively charged and electrons are negatively charged. An ion with 8 protons and 10 electons would have a charge of 2- as there are 2 more electrons than protons.As this ion has 8 protons is must have an atomic number of 8 (oxygen) so the species in question is O2-.If an ion has more protons than electrons it will be positively charged.
In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
