Use the drop-down menus shown below to complete the statements about how the number of electrons in the outer shell affects the reactivity of an element. Based on the model of the periodic table, elements in [BLANK] are the most reactive because they easily give up an electron.

Elements in [BLANK] are also very reactive because they only need to accept one electron to complete their outer shell.

The most stable elements and least reactive elements are found in [BLANK]

Third Blank Answer Choices: Group 2A, Group 4A, Group 6A, Group 8A

*Will give Brainelist*​

first let us lay out the formula for potential

and kinetic energy:

pe = mgh

ke = (mv^2)/2

where: m=mass, v=velocity, g=gravitational

acceleration, h=height

calculating for mass using the known values of

pe:

340j = m (9.81 m/s^2) (50ft) (1m/3.28ft)

m = 2.27 kg

the law of conservation of energy states that

energy is neither created nor destroyed. therefore, the change in kinetic

energy from 50 ft to 35 ft would be equal to the change in potential energy

from 50 ft to 35 ft. however it would be opposite in signs since one is losing

while other is gaining.

ke(35ft) – ke(50ft) = - [ pe(35ft) – pe(50ft]

ke(50ft) = 0 since the brick is initially at rest

ke(35ft) = 340j - 2.27kg (9.81 m/s^2) (35ft)

(1m/3.28 ft)

ke(35ft)

= 102.38 j
