Highly
Explanation:
An atom that has one electron in its valence electron shell is highly chemically reactive.
Such atoms are called Alkali metals. They occupy the first group on the periodic table and they are a bunch of metals.
- The number of electrons in the valence shell of atoms determines the reactivity of an element.
- Atoms are gained or lost or shared in order to attain an octet configuration.
- When an atom with one electron in the valence shell loses this electron, it will become stable.
- This implies that it will attain its octet.
- This makes them take part in reactions that will ensure they lose that electron.
- Examples of such atoms Li, Na, K, Rb, Cs and Fr.

Answer:
51.82
Explanation:
First of all, let's convert both vectors to cartesian coordinates:
Va = 36 < 53° = (36*cos(53), 36*sin(53))
Va = (21.67, 28.75)
Vb = 47 < 157° = (47*cos(157), 47*sin(157))
Vb = (-43.26, 18.36)
The sum of both vectors will be:
Va+Vb = (-21.59, 47.11) Now we will calculate the module of this vector:
