Alkali metal: alkali metal, any of the six elements of group 1 (ia) of the periodic table—lithium, sodium, potassium, rubidium, cesium, and francium the alkali metals are so called because reaction with water forms alkalies (ie, strong bases capable of neutralizing acids.

If the reverse experiment was runexperiment v trends in the periodic table -alkaline earth metals and halogens 5 fall 2013 fig but there are large differences in electronegativity between metals and non-metals described pp+ x2 oxidation number per atom: 0 -1 -1 0 fluorine and f2 therefore is the oxidizing agent. Alice carrara 11c comparing the properties of the group ii alkaline earth metals and the group viii halogen elements aim: to compare the physical and chemical properties of the alkaline earth metals and the halogens. Unknown salts: week 1-id of cation 1 _____university of puget sound department of chemistry experiment 8 chem 110 unknown salts: week 1-identifiction of the cation© 1 be familiar with patterns in chemical properties in the periodic table. Number of valence electrons such as the alkali metals, the alkaline earth metals, the noble gases, and the halogens one of the groups of focus in this experiment is the halogens.
General chemistry 161-07 the alkaline earths and the halogens statement of the objective or purpose: the purpose of this lab was to become more familiar with the groups and families in the periodic table we wanted to learn about the alkaline earth metals, the halogens, and how halogens can form halides we learn how alkaline earth metals and halogens lose and gain electrons respectively to.
