Which element is likely more reactive, and why?
these models show the electron structures of two different
nonmetal elements.
element 1 is more reactive because it has fewer
electron shells and is toward the top of its group on the
periodic table.
element 1 is more reactive because it has more
electrons in its valence shell and is farther to the right on
the periodic table.
element 2 is more reactive because it does not have a
valence shell close to the nucleus, so it will attract
electrons.
element 2 is more reactive because it does not have a
full valence shell, so it will attract electrons.
element 1
element 2

answer: point c: b. 1/2 potential, 1/2 kinetic, point a: 3/4 of its potential energy, point d or b: 3/4 potential, 1/4 kinetic

explanation: i cant explain. it's difficult to explain.

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

i had this question and the answer was 3.15 miles.

martina travels from school to her mom's office. from there, she walks to school. after school, she walks to the library and then to a friends house before finally ending back at home. find martina's total distance traveled.

a) 0 miles  

b) 0.4 miles  

c) 1 mile  

d) 3.15 miles
