What does sulfur have to do to become an ion?
When forming an ionic compound with one atom of sulfur, two potassium atoms are used. Each potassium atom donates its outermost electron to the sulfur atom, forming ions with a 1+ charge, due to the loss of an electron. When sulfur receives these two electrons, it is ionised itself, becoming an ion with a 2- charge.
Why does the sulfide ion have a charge?
The sulfide ion (S2-) has a charge of -2, which means that it is formed by gain of 2 electrons. Sulfur is a nonmetal from group 6A and it has 6 valence electrons. Sulfur atom gains 2 electrons to form the sulfide ion which has a complete octet.
What does sulfur do to become more stable?
In order to be stable, a particle must possess an octet, or eight, fully-paired valence electrons. Sulfur would need to gain 2 electrons in order to achieve an octet configuration. Therefore, sulfur will gain two additional valence electrons. Consider the impact that this will have on sulfur’s electron configuration.
How does the octet rule explain the formation of a sulfide ion?
(a) Sulfur ( ) has six valence electrons. If it gains two electrons to a valence shell, then it will complete the octet number. Therefore, sulfide ion ( ) has eight valence electrons in its valance shell (octet).
How does a sulfur ion S2 -) ion differ from a sulfur S atom?
Elemental sulfur, or sulfur in a neutral element has 6 electrons associated with it, and is therefore neutral. S2− ions has 8 electrons, and therefore bears a 2- minus charge.
When sulfur becomes an ion what is its charge?
2
Sulfur is in group 6 of the periodic table. What is the charge on its ions, and is the charge positive or negative? The charge is negative, since sulfur is a non-metal. The charge on the ion is (8 – 6) = 2.
When an atom of sulfur becomes an ion It electrons and has the electron configuration of?
The nearest noble gas to sulfur is argon, which has an electron configuration of: 1s22s22p63s23p6. To be isoelectronic with argon, which has 18 electrons, sulfur must gain two electrons. Therefore sulfur will form a 2- ion, becoming S2-.
What is the charge of a sulfur ion?
Why does sulfur have a 2 charge?
Since electrons carry a negative charge, gaining electrons will result in the formation of a negatively charged ion, or anion. For each electron gained, the ion’s overall charge decreases by 1 unit, which further confirms the fact that the neutral sulfur atom gained 2 electrons to get the (2−) charge.
What ion is formed from sulfur?
Sulfide
Naming monatomic anions
| Element name | Ion name | Ion formula |
|---|---|---|
| Sulfur | Sulfide | S2− |
| Nitrogen | Nitride | N3− |
| Phosphorus | Phosphide | P3− |
| Carbon | Carbide | C4− |
Why is the sulfur atom smaller than the sulfur ion?
This extra repulsion in the sulfide ion increases the average distance between the valence electrons, so the electron cloud around the sulfide ion has the greater radius.
How does a sulfur atom become a sulfide ion?
The most common ion formed from a single sulfur atom is a sulfide ion, with a charge of -2. How does an atom become negative ion or positive ion? An atom become an ion after losing or gaining electrons. How does a sulfur atom become a sulfide ion why does it have a tendency to do so?
Why does a sulfur atom have a S2 symbol?
The symbol is S2- because to become an ion a sulfur atom gains two electrons and each electron has a 1- charge. How many protons are presented in a neutral sulfur atom?
How many electrons does a sulfur atom need to be stable?
Since the negative charge of the electrons cancels the charge of the protons, the sulfur atom is neutral. The electron configuration of sulfur is “1s”^2″2s”^2″2p”^6″3s”^2″3p”^4”. The valence shell (the 3s and 3p sublevels) contains six electrons, but it needs eight to become stable. Think of the octet rule.
What happens to an atom when it loses an electron?
When an atom forms an ion it gains or loses one or more electrons and develops a negative or positive ion. If an atom gains an electron, it will become a negatively charged ion. If an atom loses an electron, it will become a positively charged ion.
