106. Carbon-12 contains 6 protons and 6 neutrons. The radius of the nucleus is approximately 2.7 fm, and the radius of the atom is approximately 70 pm. Calculate the volume of the nucleus and the volume of the atom. What per- centage of the carbon atom's volume does the nucleus occupy? (Hint: Convert both given radii to m, and then calculate their volumes using the formula for the volume of a sphere, which is V = {rr².)

Isotopes are different types of atoms of the same chemical element, each having the same number of protons and electrons but a different number of neutrons. The atomic number of an element, denoted by the symbol Z, is equal to the number of protons. The mass number of the element, denoted by the symbol A, is the sum of the number of protons and the number of neutrons. Therefore, isotopes of the same element have the same atomic number (Z), but their mass numbers (A) are different. For example, carbon has three isotopes, carbon-12, carbon-13, and carbon-14, with mass numbers 12, 13, and 14, respectively. All three isotopes have the same atomic number (Z = 6) but different mass numbers. The isotopes can be represented by using symbolic notation. In symbolic notation, the mass number is written as a left superscript and the atomic number is written as a left subscript to the chemical symbol of the element: tab Os lock Part A Atomic number 14 The isotopes of carbon with mass numbers 12,…
Let's attempt to assemble the composition of the Boron atom. The atomic number of Boron is 5, the mass number is 11, and the overall charge of the atom is zero. This means that Boron has 5 protons, 5 electrons, and 6 neutrons. In a plate, place 5 pieces of calamansi fruits. These will be our protons. Then place 6 pieces of lanzones fruits. These will be our neutrons. Then add 5 pieces of rice grains. These will be our electrons. Now try to assemble the components of a Fluorine atom. Its atomic number is 9, its mass number is 19, and its overall charge is –1. Describe the contents of your plate.

Three samples (A, B, and C) of pure substance composed ofsodium, sulfur, and oxygen were isolated and purified. Elemental analyses showed that sample-A contained 1.62 g sodium, 1.13 g sulfur and 2.25 g oxygen; sample-B contains 1.60 g sodium,2.23 g sulfur, and 1.67 g oxygen; while sample-C contains 1.46 g sodium, 1.02 g sulfur, and 2.03 g oxygen. Determine whether A, B,and Care samples of the same or different compounds.
A sample of lithium consists of 400 atoms. 30 atoms are the isotope Lithium-6 (6.015 amu) and 370 are Lithium-7 (7.016 amu). Which student correctly calculated the correct average atomic mass and why? Student 1 calculated the average atomic mass as 6.94 amu. Student 1 determined the percent abundance for each isotope and then multiplied the percent abundance by the average atomic mass of its isotope and took the sum. Student 2 calculated the average atomic mass as 6.52 amu. Student 2 took the average of the mass of the two isotopes of lithium. Student 3 calculated the average atomic mass as 1.06 amu. Student 3 took the sum of the average atomic masses of the isotopes and multiplied by the ratio of lithium-6 to lithium-7. Student 4 calculated the average mass as 13.0 amu. Student 4 added the mass of the two isotopes.
An atom has a diameter of 3.00 Å and the nucleus of that atom has a diameter of 7.50 × 10-5 Å. Determine the fraction of the volume of the atom that is taken up by the nucleus. Assume the atom and the nucleus are a sphere. fraction of atomic volume: Calculate the density of a proton, given that the mass of a proton is 1.0073 amu and the diameter of a proton is 1.69 × 10-¹5 m. density: g/cm³
An atom has a very small nucleus surrounded by an electron "cloud." The figure below represents the nucleus with a diameter of about 2 mm and describes the electron cloud as extending over 200 m. If the diameter of an atom is 1 x 10-° cm, what is the approximate diameter of its nucleus? Nucleus with protons (positive electric charge) and neutrons (no electric charge). Electrons (negative electric charge). The number of electrons and protons is equal in an electrically neutral atom. Diameter cm
11. Identify as true (T) or false (F): Minerals separating from flowing water as stony deposits represents a physical change. A pure substance may be made of a single element or of a single compound. Atoms of different elements must have different numbers of protons in their nuclei. The smallest piece we can separate from an atomic substance physically is an atom.
J.J Thomson determined the charge-to-mass ratio of the electron to be 1.759*1011 coulombs/kg. The mass of an electron is 9.107*10-31 kg. What must be the charge on the electron, C, in coulombs?
There are two isotopes of the element lithium that occur naturally, 6Li (mass = 6.015 amu) and 7Li (mass = 7.016 amu). Given that the average atomic mass of lithium is 6.941 amu, what are the fractional abundances of the lithium isotopes?
