Why are components of vectors scalars? Lets say we have a vector 1i+2j, I saw that the components of the vectors are said to be scalars, how can that be possible, doesnt 1i have a direction, also if they were a scalar why are the following vector laws of addition,
The components in this context aren't $1\mathbf i$ and $2\mathbf j$, but $1$ and $2$.
And indeed, $\mathbf i$ and $\mathbf j$ are vectors, which can be (and are) scaled to make linear combinations.
The components of $1 \hat{i}+2\hat{j}$ are $1,2$ and not $1  \hat{i}, 2\hat{j}$

Components of vectors are not scalars, and not vectors- they are simply components of vectors.
Scalars are objects who do not change under change of coordinates (e.g. if you rotate the axes by some angle). The components of a vector do change.
Example:
if we take some cartesian coordinates $x,y$, and the vector $\vec{V}= 2 \hat{x}+5\hat{y}$, if we take $x',y'$ to be coordinates which are rotated by $\pi/2$ we get $\vec{V}= 5 \hat{x'}-2\hat{y'}$. The components changed.  The vector length, hoever, is a scalar, as you can check.
