Which three elements represented in graph 1 do not have a value for electronegativity? explain why. (be sure to include their location on the periodic table and the definition of electronegativity) 1pt -- list the atomic numbers of elements in period 2 of the periodic table. locate the atomic numbers on your graph. what is the general trend in electronegativity as the atomic number increases across period 2? 2pts -- list the atomic numbers of elements in group 2 of the periodic table. locate the atomic numbers on your graph. what is the general trend in electronegativity as the atomic number increases down group 2? 2pts

Hydrogen, helium, neon. electronegativity means ability to attract electrons.

helium, & neon do not need anymore electron. they are in column 8. Hydrogen is in column 1 but it depends on what it is reacting with to gain  or lose an electron.

3,4,5,6,7,8,9,10  electronegativity increases

As you go down a group the electronegativity decreases

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
