Question

PhET simulation window, verify that the Atom option is highlighted in the navigator bar at the bottom of the page. This view has information blocks for net arge and mass number. Drag protons, neutrons, and electrons from their respective bins onto the area above them to determine how an atom is structured. match the words to the appropriate blanks in the sentences below. Make certain each sentence is complete before submitting your answer. neutrons protons two electrons four protons, neutrons, and electrons protons and neutrons electrons and neutrons six eight protons and electrons 1. An atom (derived from the Greek word atomos meaning indivisible) is the smallest unit of matter that cannot be further broken down and still retain the same characteristics and identity of its original element. Its components are the subatemic particles knowm as 2. are both centrally located in an aatom's nucleus, while surround the nucleus in designated shells (which are commonly thought of as "orbits" as labeled in thePhET simulation). 3. The innermost shell can hold up to particles, and the second shell (which isn't filled until the first is completely full) is farther from the nucleus and can hold up to particles. 4. The number of , known as the atomic number, determine the elemental identity of an atom. 5. For example, an atom with three is identified as a lithium atom. Its atomic symbol is displayed as Li. The atomic number is the basis behind the ordering of elements within the periodic table.
