What do you get when you combine two sodium atoms?
Terms
- polyatomic ionAn ion composed of several atoms.
- empirical formulaThe simplest whole-number ratio between elements in a formula of a compound.
- noble gasAny of the elements of group 18 of the periodic table, which are monatomic and, with very limited exceptions, inert, or non-reactive.
When a sodium atom becomes an ion it does what?
When sodium forms an ion, it will form Na+ a cation. Furthermore, is sodium chloride an ion? Sodium chloride or NaCl is an ionic compounds made up of sodium (Na) and Chloride (Cl) ions. An atom can lose an electron and attain a positive charge to become a cation.
What happens when two sodium atoms move toward one another?
Two electrons move toward one another. An electron moves away from a proton. Two neutral sodium atoms move toward one another. A cation moves toward an anion. decreases no change increases decreases no change increases decreases no change increases decreases no change increases decreases no change increases
When are atoms most likely to form ions?
Ions form when atoms lose or gain electrons to obtain a full outer shell: For elements in groups 1, 2 and 3, the number of electrons lost is the same as the group number. For elements in groups 6 and 7, the charge on the ion is equal to (8 minus group number).
How did sodium become an ion?
A neutral sodium atom, for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na+ ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged.
How does the sodium atom become an ion and what is its charge?
Tell students that when an atom gains or loses an electron, it becomes an ion. Sodium loses an electron, leaving it with 11 protons, but only 10 electrons. Since it has 1 more proton than electrons, sodium has a charge of +1, making it a positive ion.
Why does sodium form a 1+ ion?
A sodium atom can lose its outer electron. It will still have 11 positive protons but only 10 negative electrons. So, the overall charge is +1. A positive sign is added to the symbol for sodium, Na +.
Does sodium form ionic bonds?
A sodium atom can only form one ionic bond, because it only has one electron in its outer shell to donate. 4. The reason a bond is formed between chloride ions and sodium ions is because an electron has been transferred between them.
