This statement is true<\/strong>. Both atoms have the same number of protons, which determines the element’s identity. In this case, both atoms have 12 protons<\/strong>, which makes them both carbon atoms<\/strong> (the atomic number of carbon is 12). However, the difference between them is the number of neutrons<\/strong>. The first atom has 12 neutrons<\/strong>, and the second atom has 13 neutrons<\/strong>. Atoms of the same element that have different numbers of neutrons are known as isotopes<\/strong>. Therefore, the two atoms described are isotopes<\/strong> of carbon.<\/li>\n\n\n\n
This statement is false<\/strong>. As mentioned above, both atoms have 12 protons<\/strong>, which means they are both carbon atoms<\/strong>, not different elements. The element is defined by the number of protons, so having the same number of protons means both atoms are the same element (carbon), despite having different isotopes.<\/li>\n\n\n\n
This statement is false<\/strong>. The mass of an atom is primarily determined by the sum of its protons and neutrons. The first atom has 12 protons<\/strong> and 12 neutrons<\/strong>, giving it a mass number of 24<\/strong>. The second atom has 13 protons<\/strong> and 13 neutrons<\/strong>, giving it a mass number of 26<\/strong>. Therefore, the second atom is heavier than the first atom, not the other way around.<\/li>\n\n\n\n
This statement is false<\/strong>. Both atoms are described as having 12 electrons<\/strong>, which balances out the 12 protons<\/strong> in each atom, meaning both atoms are neutral<\/strong>. For an atom to have a positive or negative charge, it would need to lose or gain electrons, respectively. Since both atoms have an equal number of protons and electrons, neither atom has a charge.<\/li>\n\n\n\n
This statement is false<\/strong>, because the third statement (that the first atom is heavier) is incorrect, as explained above.<\/li>\n<\/ol>\n\n\n\nConclusion:<\/h3>\n\n\n\n
