User: Elements from which two families would most likely combine with each other to create salts?Īlkali metals and alkaline-earth metals Weegy: Alkali metals and halogens would most likely combine with each other to create salts. For example: Find the supplementary angle of 33 degrees. These two angles are called supplements of each other. Supplementary angles are two angles that add up to 180 degrees. Supplementary angles refer to the pair of angles that always sum up to 180. Similarity in melting point Weegy: Similarity in properties is used to arrange the elements in columns on the periodic table. A 'Supplementary Angle Calculator' is an online tool that finds and displays the supplementary angle of the given angle. For example, the angles with 120 and 60 are supplementary. User: What criterion is used to arrange the elements in columns on the periodic table? Two angles are considered supplementary when the sum of their measures is equal to 180. Y Weegy: Te (Tellurium) is a Group A element. User: Of the elements Fe, Hg, U, Te, and Y, which is considered a Group A element? Increase because additional energy levels are filled. Increase because electrons are gained from other atoms. What is the measure of an angle, if three is subtracted from twice the supplement and the result is 297 degrees Solution: Translate the problem slowly phrase. User: From top to bottom in most groups of elements, atomic radii tend toĭecrease because the nuclear charge increases.ĭecrease because electrons are lost to other elements. You may select whole numbers or decimal numbers for the. User: Who first arranged the elements according to nuclear charge?ĭmitri Mendeleev Weegy: Dmitri Mendeleev arranged the elements according to nuclear charge. This Angles Worksheet is great for practicing finding missing angles from supplementary angle pairs. Weegy: Each horizontal row of elements in the periodic table is called Period.
