The mass of an atom of element x is equivalent to the total mass of 7 hydrogen atoms.<\/p>\n\n\n\n
The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n If the mass of an atom of element X is equivalent to the total mass of 7 hydrogen atoms, we can determine the approximate atomic mass of element X based on the atomic mass of hydrogen.<\/p>\n\n\n\n The atomic mass of a hydrogen atom (H) is approximately 1 atomic mass unit (amu)<\/strong>. This is because hydrogen is the lightest element and consists of just one proton (and, in most cases, no neutrons).<\/p>\n\n\n\n Since one hydrogen atom has a mass of 1 amu, the mass of 7 hydrogen atoms would be:<\/p>\n\n\n\n [ Thus, the mass of element X is 7 amu<\/strong>.<\/p>\n\n\n\n Now that we know the atomic mass of element X is approximately 7 amu, we can identify it. By looking at the periodic table, the element with an atomic mass close to 7 amu is lithium (Li)<\/strong>, which has an atomic mass of approximately 6.94 amu<\/strong>.<\/p>\n\n\n\n The atomic mass of an element is largely determined by the number of protons and neutrons in the nucleus, since electrons have a negligible mass. Hydrogen, the simplest atom, consists of just one proton. Heavier elements, like lithium, have more protons and neutrons, which increases their atomic mass. In this case, the mass of element X being equal to 7 hydrogen atoms suggests that X has a similar mass to lithium<\/strong>.<\/p>\n\n\n\n Lithium has 3 protons and 4 neutrons, giving it an atomic mass close to 7 amu. It is a member of the alkali metal group and is commonly used in batteries and other electronic applications. Thus, based on the given information, element X is most likely lithium.<\/p>\n","protected":false},"excerpt":{"rendered":" The mass of an atom of element x is equivalent to the total mass of 7 hydrogen atoms.
