Scientists continue to investigate atoms and have discovered even smaller constituents of which neutrons and protons are made. Atoms form bonds to other atoms by transferring or sharing electrons. An atom's electron configuration, particularly the outermost electrons, determines how the atom can interact with other atoms. The number of protons in the nucleus determines what an atom's electron configuration can be and so defines the element. The nucleus is composed of protons and neutrons which have roughly the same mass but differ in that protons are positively charged while neutrons have no electric charge. The nucleus is a tiny fraction of the volume of an atom but makes up almost all of its mass. Atoms are made of a positively charged nucleus surrounded by negatively charged electrons. The atoms of any element are like other atoms of the same element, but are different from the atoms of other elements. All matter is made up of atoms, which are far too small to see directly through a microscope. The periodic table has a great deal of information about every atom. Isotopes Same Atom, Not Isotopes of Each Other Different ElementĮXERCISES16. Then see how concentration and strength affect pH. Test your understanding of isotopes by examining the relationships between the pairs of atoms listed below:Ītom 1 Atom 2 Relationship between atom 1 and atom 2 Isotopes Same Atom, Not Isotopes of Each Other Different ElementĬarbon-12 Isotopes Same Atom, Not Isotopes of Each Other Different ElementĪrgon-40 Argon-41 Isotopes Same Atom, Not Isotopes of Each Other Different Elementīoron-10 Isotopes Same Atom, Not Isotopes of Each Other Different Element How do strong and weak acids differ Use lab tools on your computer to find out Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Based on this information, list the requirements for two atoms to be isotopes of each other.ġ5. The atoms in the previous question are isotopes of each other. Name _ # attempts to score 100% _ Game 4ġ4. Play until you can get all the questions correct on the 4th level. Practice applying your understanding by playing the 3rd and 4th game levels. Create a definition or mathematical expression for each of these items based on your labelsġ0. Build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. The particle(s) used to determine the letter, and how the value of each letter is determined (which you will answer in question 9)Ī= _ b= _Ĭ = _ d =_ĩ. Do this by adding and removing particles until you have come up with a conclusion.a) In the atomic symbol below, label each letter (a, b, c, and d) with: Click on the Symbol readout box (located to the left of the game box), figure out which particles affect each component of the atomic symbol. Negative ions have _ protons than electrons.Ĩ. Positive ions have _ protons than electrons. Neutral atoms have the same number of protons and electrons. a) Fill in the blanks below to show your results: You can see the charge of the atom in the upper right hand corner of the model. An atom with a charge is called an ion (it can be either positive or negative!). Play with the simulation to discover which particles affect the charge of an atom. What is the element symbol of the following atoms?a) An atom with 3 protons and 4 neutrons: _b) An atom with 2 protons and 4 neutrons: _c) An atom with 4 protons and 4 neutrons: _ĥ. Play until you discover which particle(s) determine(s) the name of the element you build. Changed + to -.)) Select the to start over.2.Ī) List two things your group observed in the simulation.i.ī) What particle(s) are found in the center of the atom and what is their charge(s)?Ĭ) What particle(s) are found outside the center of the atom and what is their charge(s)?ģ. As you explore, talk about what you find. Explore the Build an Atom simulation with your group. PART I: ATOM SCREEN Build an Atom simulation ()ġ. BUILD AN ATOM – GOOGLE PHET BUILD AN ATOM
