What occurs when a chlorine atom becomes a chloride ion?
Since each chlorine atom gained an electron, they each have 17 protons and 18 electrons. This makes each chloride a negative ion with a charge of −1. Oppositely charged ions attract each other, forming an ionic bond.
What is the charge when chlorine forms the chloride ion?
(–1)
Again, it is more energy-efficient for chlorine to gain one electron than to lose seven. Therefore, it tends to gain an electron to create an ion with 17 protons, 17 neutrons, and 18 electrons, giving it a net negative (–1) charge. It is now referred to as a chloride ion.
What occurs when an atom of chlorine and an atom of hydrogen become a molecule?
What occurs when an atom of chlorine and an atom of hydrogen become a molecule of hydrogen chloride? A chemical bond is formed and energy is released.
Why is chlorine ion different from chlorine atom?
What is the difference between Chlorine Atom and Chloride Ion? Chloride ion is the reduced form of chlorine atom. Chloride has 18 electrons compared to seventeen electrons of chlorine, and both have seventeen protons. Therefore, chloride has a negative (-1) charge whereas chlorine is neutral.
How does a chlorine atom differ from a chlorine ion?
A neutral chlorine atom, for example, contains 17 protons and 17 electrons. By adding one more electron we get a negatively charged Cl- ion with a net charge of -1. The gain or loss of electrons by an atom to form negative or positive ions has an enormous impact on the chemical and physical properties of the atom.
How does a chlorine atom differ from a chloride ion the chlorine atom has?
Which type of bond is formed between the two chlorine atoms in a chlorine molecule?
covalent bond
The two chlorine atoms are said to be joined by a covalent bond. The reason that the two chlorine atoms stick together is that the shared pair of electrons is attracted to the nucleus of both chlorine atoms.
What types of ions will sodium and chlorine each form explain?
Sodium has 1 electron in its outermost shell, and chlorine has 7 electrons. It is easiest for sodium to lose its electron and form a +1 ion, and for chlorine to gain an electron, forming a -1 ion.
What occurs when an atom loses an electron?
An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (see page 10 for more on ions).
Which process produces a chlorine ion?
electrolysis
Chlorine can be manufactured by the electrolysis of a sodium chloride solution (brine), which is known as the Chloralkali process. The production of chlorine results in the co-products caustic soda (sodium hydroxide, NaOH) and hydrogen gas (H2). These two products, as well as chlorine itself, are highly reactive.
