Metals at the bottom of a group lose electrons more easily than those at the top. of Sodium, Magnesium, and Aluminum (kJ/mol). No. Na + ( aq ) + Cl - ( aq) The only question is whether it is legitimate to assume that this reaction occurs because chlorine atoms "like" electrons more than sodium atoms. How does a sodium ion differ from a sodium atom? That is, ionization energies tend to decrease in going from the top to the bottom of a group. Forming ions - Metals, non-metals and compounds - GCSE Chemistry - BBC The sodium loses an electron, and the chlorine gains that electron. From that point on, however, the electron Does sodium become a positive or negative ion? Which is correct poinsettia or poinsettia? 1 What happens for sodium to form a positive ion? charged ions. When elements with very different electronegativities (such as fluorine and cesium) react, one or more electrons are transferred to form an ionic compound. There are no abrupt changes in the physical properties discussed in this chapter as we Which one is the cation and which is the Why does bromine have a larger atom than chlorine? Electron affinities generally become smaller as we go down a column of the periodic periodic table from left to right, while nonmetallic character increases. see a solution to Practice Problem 3.

Ionic bonds are formed between ions with opposite charges. 8]+. To form an ion, a sodium atom: a. gains one electron b. gains two How does sodium become an ion? The Periodic Table When one or more electrons is stripped away from an atom, it becomes positively charged. How do a sodium atom and a sodium ion differ? A sodium atom can lose its outer electron. They often form molecules in their elemental form. There are sodium channels in the membrane, but they are initially closed. Compound ions Those ions which are formed from groups of joined atoms are called compound ions Example: Ammonium ion NH 4 +, is a compound ion which is made up of two types of atoms joined together, nitrogen and hydrogen. ).
