Both calcium and magnesium have <strong>two electrons in their outermost shell<\/strong> (valence shell). This makes them likely to form <strong>+2 ions<\/strong> (Ca\u00b2\u207a and Mg\u00b2\u207a) by losing these two electrons during chemical reactions.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Alkaline Earth Metals:<\/h4>\n\n\n\n<p>The alkaline earth metals include:<br><strong>Beryllium (Be), Magnesium (Mg), Calcium (Ca), Strontium (Sr), Barium (Ba), and Radium (Ra)<\/strong><\/p>\n\n\n\n<p>These metals share the following properties:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>They are shiny, silvery-white metals.<\/li>\n\n\n\n<li>They are somewhat reactive, especially with water (increasing reactivity as you move down the group).<\/li>\n\n\n\n<li>They form <strong>basic (alkaline) oxides<\/strong> and <strong>hydroxides<\/strong>.<\/li>\n\n\n\n<li>They commonly form ionic compounds.<\/li>\n<\/ul>\n\n\n\n<p>Since magnesium is just above calcium in the periodic table, they have <strong>similar atomic structures<\/strong>, with calcium having an additional electron shell. However, their chemical properties remain closely related.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Why the Other Options Are Not Similar:<\/h4>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>b. B (Boron):<\/strong> A Group 13 element; metalloid with 3 valence electrons.<\/li>\n\n\n\n<li><strong>c. Ar (Argon):<\/strong> A noble gas (Group 18), very unreactive, completely different behavior.<\/li>\n\n\n\n<li><strong>d. Br (Bromine):<\/strong> A halogen (Group 17), a reactive non-metal forming \u22121 ions.<\/li>\n\n\n\n<li><strong>e. Al (Aluminum):<\/strong> A post-transition metal in Group 13, forming +3 ions.<\/li>\n<\/ul>\n\n\n\n<p>These elements differ in their group, valence electron count, and general chemical behavior, making them chemically dissimilar to calcium.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Conclusion:<\/h3>\n\n\n\n<p><strong>Magnesium (Mg)<\/strong> is chemically similar to calcium because they are both <strong>alkaline earth metals<\/strong> in the same group with similar physical and chemical properties.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of these elements is chemically similar Ca? a.
