Atomic Structure Review
Subatomic Particles Match the definition to the correct term. positive charge proton negative charge electron neutral charge neutron center part of the atom nucleus smallest unit of matter atoms Where do you find me? Sort where each subatomic particle would be found in the atom. Inside the Nucleus protons neutrons Outside the Nucleus electrons electron cloud A proton is... positively charged, with a smaller mass than an electron positively charged, with a larger mass than an electron negatively charged, with a smaller mass than an electron negatively charged, with a larger mass than an electron A lithium nucleus contains 3 protons and 4 neutrons. What is its atomic mass? 7 4 3 1 Which is the correct symbol for the element magnesium (atomic #12)? M MG Mg Ma Model of an atom Click each subatomic particle and label it. neutron proton electron How many protons are there in the atom below? How many neutrons are there in the atom below? How many electrons are there in the atom below? What is the atomic mass of an atom with 9 protons and 11 neutrons? 9 11 20 21 Atomic Mass Match the subatomic particle with its amu proton 1 amu and positive neutron 1 amu and neutral charge electron 0 amu massless and negative Subatomic Particles Click on the dots to fill in the blanks. Type the words EXACTLY like in the word bank: positive, negative, neutral, 1 amu, 0 amu, 1 amu, nucleus, electron cloud nucleus nucleus electron cloud positive neutral, no charge negative 1 amu 1amu 0 amu Atomic Structure Click on the dots to label the atom - nucleus, electron cloud, proton, neutron, electron proton neutron nucleus electron cloud electron A neutral atom contains 12 electrons, 12 protons, and 15 neutrons. What is the atomic mass of this atom? 27 amu 12 amu 15 amu 3 amu What type of particles are found in the cloud surrounding the atom's nucleus? positive and negative particles negative particles only neutral and positive particles positive particles only Which of these is NOT found in the nucleus of an atom? proton nucleus the mass of the atom electrons
