WebLi, Na, K, Rb, and Cs are all group IA elements, also known as the alkali metals. The seventh member of the group, francium (Fr) is radioactive and so rare that only 20 atoms of Fr may exist on Earth at any given moment [1]. The term alkali is derived from an Arabic word meaning “ashes.”
WebThe metals in groups 1A, 2A, and 3A: A) gain electrons when they form ions B) form ions with a charge found by subtracting 8 from the group number C) all form ions with a 1+ … WebIf you look at the periodic table above you will note that the Group 1A, 2A and 3A elements all form positive ions or Cations. This is because it is easier energetically for those elements to lose 1, 2, or 3 electrons than it would be for them to gain 5, 6 or 7 electrons.

These are (except for hydrogen) soft, shiny, low-melting, highly reactive metals, which tarnish when exposed to air.
WebThere are a number of important physical and chemical properties of the elements that vary in a periodic way across the periodic table. For example, elements in Group 1A all tend to participate in similar chemical reactions with water, 2M (s) + H 2 O (l) ® MOH (aq) + H 2 (g) as do the Group 2A elements, M (s) + 2H 2 O (l) ® M (OH) 2 (aq) + H 2 (g)
