Please answer question 11 part A and B Review I Constants I Periodic TableLearning Goal:To understand the arrangement of the periodictable and identify certain groups of elements byname (e.g. halogens, metals, lanthanides etc.).Groups and periodsThe periodic table is a list of elements arranged byatomic number. As you can see in the image(Figure 1) below, the atomic number for eachColumns in the periodic table are called groups, and the rows are called periods. Notice that the groups are labeled 1 to 18and the periods are labeled 1 to 7. Groups 1, 2, and 13 to 18 are called the main group elements, groups 3 to 12 are thetransition elements, and the bottom two rows are called the lanthanides and actinides, respectively.element is the whole number in the cell. The atomicThis table gives properties and alternate names for some of the groups:mass, written below the symbol here although itmay appear elsewhere in some periodic tables, isthe average mass of the isotopes of that element.GroupNameProperties1Alkali metalsReact to form 1+ ions.2Alkaline earthsReact to form 2+ ions.17HalogensReact to form 1– ions.Rare gases(noble gases)Stable and unreactive. (Elements fromother groups form ions to achieve thesame number of electrons as a noble gas.)18Metals vs. nonmetalsNotice the heavy zigzag line running diagonally across the right part of the table. This line separates metals (below and to theleft of the line) from the nonmetals (above and to the right of the line). Metals tend to lose electrons to form positive ions,whereas nonmetals tend to gain electrons to form negative ions.Figure1 of 1atomic numberH.1.008- atomic mass Part AWhat is the atomic number of the element located in group 16, period 2 of the periodic table?Enter the atomic number.• View Available Hint(s)Part BIf a new element were discovered and it was found to form 1– ions, in which group would you place it in the periodictable?Enter the group number.View Available Hint(s)

Most analytical machines used in science can either measure absorbance of light, like the spectrophotometers used BioZ 151 and 152 labs, or can measure change in electrical conductance. In order to convert things like absorbance values into concentration data, a linear regression is used. In order to determine nitrite concentration in water samples, nitrite is reacted with several chemicals to produce a purple color. The absorbance of the solution is measured from known amounts of nitrite to produce a standard curve to analyze samples. Use the data in the provided table, or from the linked spreadsheet to make a graph and perform a linear regression using treadline. mg/L NO3 Absorbance 0 0.1 0.3 0.5 0.7 o 0.183 0.542 0.914 1.298) 1.61) In order for this to work, samples must be diluted prior measurement so that the concentration falls within the range of the standard curve.
