What type of chord is this?

[driz]

My mom was playing piano and said she had a hard time with this type of chord, she called it a broken chord but when I looked it up it was actually not a broken chord.

I don't know what it is...

Out of curiosity, does anyone know what kind of chord it is when one note seems to be off-key?

Is that even considered a chord? What is it, if it's not a chord?;;

broken chords as i commonly use the term refers the technical exercise, sort of like an arpegio however you hit each inversion on your way up to the next octave,

i.e. c-e-g,e-g-c,g-c-e, repeat, etc. etc.

if you're refering modified chords it depends on which tone is changed, i.e you can augment (raise a half step) or diminish (decrease half step), in jazz and pop you will normally see these written as the root chord then either #__(insert tone, i.e. #2 = sharp second), or b___(i.e. b9=flat 9th).

in modern art music it is almost entirely context dependent especially in chords that do not fit traditional tonality you will come across named chors like german sixth chord, neapolitan chords, even work specific such as the 'tristan chord' , scriabin had  the Mystic chord or Prometheus chord ( a complex, six-note quartal chord, scale, or pitch collection which served loosely as the harmonic and melodic basis  =C, F♯, B♭, E, A, D)

If you want an accurate answer, I'd suggest asking the question more precisely (or give some examples).  Right now, no clue what you are asking about.

I think Cluster chord might be one possible option.

I'm sorry I suppose it did sound a bit vague...

but from what my mother did, I'm not quite sure on the exact notes.

Simply that she referred to the chord as a broken chord, and from what I saw, it was a tri-note chord and the first or fifth of it was off.

Like instead of a C Major chord being C, E, G, it was like...(and this is an example because I don't remember what note she used) C, E, A# or... A#, E, G...

Is that a still a type of chord?

It sounds like a suspension to me.

Instead of C, E, G, you play C, D, G (C2) or C, F, G (C4) then you "resolve" to the major chord. 

[nystul]

Well it depends really on the exact intervals as to what kind of chord it is.  CEBb is a C7 (dominant seventh chord) with the fifth omitted.  CEG# would be an augmented chord.  You could come up with a different chord name for just about any group of notes these days. 

But broken chord is basically another way of saying arpeggio.
