Which of the following stotements about electronegativity and the periodic table is true? O Electronegativity decreases across a row of the periodic table O Electronegativity increases down a column of the periodic table O Electronegativity increases across a row of the periodic table O Electronegativity does not change down a column of the periodic table
The periodic trends of electron affinity and electronegativity are often confused by chemistry students. If you were responsible for teaching a first-year experience class in chemistry, how would you explain the similarities and the differences between these two properties? It would be a mistake to simply restate the textbook definitions; convince me that you understand the differences! (4 pts)
12. What are the periodic trends for atomic size, ionization energy, and electron affinity moving from TOP to BOTTOM of the periodic table? (Write Increases or Decreases) Atomic Size: cncceases Ionization Energy: Electron Affinity: _decreases
Font Paragraph F Styles Data Sheet Table 1: Periodic Trends Periodicity Observation What are the Group 1 elements called? Within a group, what happens to the atomic radius as you go down the column? Within a period, what happens to the atomic radius as the atomic number increases? What is the general trend of electronegativity as you go left to right across the periodic table? What is the general trend of electronegativity as you go down the periodic table? What...

Circle the atom with the more favorable Electron Affinity, I or Br. d. Circle the atom with the largest Effect Nuclear charge, Be or N. e. Circle the atom with the largest Electronegativity, S or P. 8. Answer each of the following using only...
Periodic Trends in Relative Electron Affinity Part B Electron affinity, EA, is the energy required to add an electron to a neutral gaseous atom and is related to an element's position on the periodic table. Electron affinities can be positive, negative, or zero, as shown in the table. Electron affinity Element (kJ/mol) N (nitrogen) >0 Br (bromine) -325 Sr (strontium) -5 Rank the following elements by electron affinity, from most positive to most negative EA value. Rank from most positive...

Effective Nuclear Charge and Periodic Trends Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. ? ∝ ?1?2/? For atoms, we’ll label the charges as the nuclear charge and electron charge. ? ∝ ?????????/? As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. ???? = ? ∙ (+1)...
