The elements found in the Group 1, or the Alkali Metal Group, have electronic configurations that end in 
.This means that they have 1 electron readily available to release in order to achieve a stable state.
When these atoms release the valence electron, they will achieve a stable state. For example, Lithium's stable state will be
and Sodium will be 
.
The oxidation state will then be +1.
The answer is C.

The answer is C.
We are given the following conditions:
Since we are told it slows down at a constant rate, we know we are dealing with uniformed accelerated motion, or UAM for short.
So we look at our kinematics equation that contains the given variables.
This contains our target variable and our initial conditions. Plug and chug, we get:
Thus the answer is:
a = -7m/s^2
Hope this helps!
