How many protons and neutrons does lithium have?<\/p>\n\n\n\n
The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n Correct Answer:<\/strong> Atoms are composed of three main subatomic particles: protons<\/strong>, neutrons<\/strong>, and electrons<\/strong>. The number of protons<\/strong> in an atom determines the element’s identity<\/strong> and is called the atomic number<\/strong>. For lithium (chemical symbol Li<\/strong>), the atomic number is 3<\/strong>, which means every lithium atom has 3 protons<\/strong>.<\/p>\n\n\n\n Protons are positively charged<\/strong> particles located in the nucleus of an atom. Since atoms are electrically neutral overall, lithium also has 3 electrons<\/strong>, which are negatively charged and orbit the nucleus.<\/p>\n\n\n\n The number of neutrons<\/strong>, on the other hand, can vary among atoms of the same element. Atoms with the same number of protons but different numbers of neutrons are called isotopes<\/strong>. The most common isotope of lithium is lithium-7 (\u2077Li)<\/strong>. The number 7<\/strong> represents the mass number<\/strong>, which is the total number of protons and neutrons in the nucleus.<\/p>\n\n\n\n To find the number of neutrons: Number of neutrons=Mass number\u2212Atomic number\\text{Number of neutrons} = \\text{Mass number} – \\text{Atomic number} Neutrons in \u2077Li=7\u22123=4\\text{Neutrons in \u2077Li} = 7 – 3 = 4<\/p>\n\n\n\n So, lithium-7 has 3 protons<\/strong> and 4 neutrons<\/strong>.<\/p>\n\n\n\n There is also a less common isotope, lithium-6 (\u2076Li)<\/strong>, which has 3 protons<\/strong> and 3 neutrons<\/strong>. However, lithium-7 is more abundant (about 92.5% of natural lithium), so it is typically used when discussing the element’s standard atomic structure.<\/p>\n\n\n\n Understanding the number of protons and neutrons is essential in chemistry and physics because it affects an element\u2019s stability, reactivity<\/strong>, and atomic mass<\/strong>. Lithium, with its light weight and unique electron configuration, is widely used in batteries, psychiatric medication, and nuclear reactions.<\/p>\n","protected":false},"excerpt":{"rendered":" How many protons and neutrons does lithium have?
