The answer is Magnesium (Mg), It has a valency of 2, which is the same as the group (a) Na (b) Mg (c) AI (d) Si Also, Mg, when combined with chloride, forms Magnesium Chloride ( MgCl2).
The atoms lose their electrons more readily, hence the right response is c. The claim that atoms lose electrons more readily is untrue since the non-metallic character rises as we move from left to right across the periods of the periodic table. As a result, there is less of a tendency to lose an electron.
Be and Ga are to be the most metallic. In Be and Ga, Ga is bigger in size and hence has a greater tendency to lose electrons than Be. Therefore, Ga is more metallic than Be.
Lithium (Li) and Beryllium (Be) are the metals among the first ten elements in the Modern Periodic Table.
(a) Since they only have one valence electron in their outermost shells, they are very unstable. Due to their easy reaction with water, hydrogen is released. They are also called alkali metals. In order to release hydrogen, they rapidly react with water.(b)They are quite stable since their outermost shells are full. They only react under …
(a) Lithium (Li), Sodium (Na) and potassium (k) have one electron in their outermost shells.(b) Magnesium (Mg) and Calcium (Ca) have two electrons in their outermost shells.(c) Neon (Ne), Argon ( Ar ) and Xenon ( Xe ) have 8 electrons means filled the outermost shells.
Calcium (Ca) and Beryllium(Be) are similar to Magnesium (Mg) because all three elements belong to the same group and have two (2) valence electrons in their outermost shell.
(a) The elements are arranged in the Modern Periodic Table according to increasing atomic number. This eliminates the oddity relating to specific elemental pair pairs in Mendeleev\’s periodic table. (b) Nickel has an atomic number of 28 and cobalt has an atomic number of 27. Therefore, despite having a larger atomic mass than nickel, cobalt …
Due to their inertness and low atmospheric concentration, noble gases are classified into a separate groups. To order to prevent them from affecting the natural order, they are confined to a separate group called the Zero group.
Mendeleev concentrated on various compounds created when different elements combined with oxygen and hydrogen. He noted the relationship between the atomic masses of various elements while developing his periodic table, among other physical properties.
