Add to me one and I'll become a mess;
Add thirty-five, I'll get bolder and louder;
Add to me none, and I'm left as a powder.

What am I?

• 1+6+35 = 42! The Answer to the Ultimate Question of Life! – Mark N May 6 '15 at 20:45

As has been pointed out, this is referencing the Periodic table... but the other answers got the references backwards.

Ash

Add to me one and I'll become a mess;

1 on the periodic table is Hydrogen, H. H+ash = Hash, a synonym for mess.

6 on the periodic table is Carbon, C. C+ash = Cash, something you buy a dress with.

Add thirty-five, I'll get bolder and louder;

35 on the periodic table is Bromine, Br. Br+ash = Brash, a synonym for "bold" and "loud".

Add to me none, and I'm left as a powder.

This one is more literal, as Ash is a powder.

• Exactly what I was going for, congrats. :) – Bailey M May 7 '15 at 14:40
• Nice! I was trying "dust" from the last line, but didn't think of "ash" or of adding letters in the way you did. +1 – Rand al'Thor May 8 '15 at 8:52

Are you

Carbon?

Add to me one and I'll become a mess;

add Hydrogen to carbon and you get hydrocarbons like oil, which is very messy

Carbon bonded with itself can be a diamond

Add thirty-five, I'll get bolder and louder;

Carbon and bromine make a purple color, which is bold.

Add to me none, and I'm left as a powder.

I'm guessing this is graphite powder

• We both came up with the idea of using the periodic table almost simultaneously! I was in the middle of writing my answer when yours went up. – Rand al'Thor May 6 '15 at 22:39
• Good instinct to go with the periodic table, but my answer is much more wordplay and much less science. Your fits perfectly, though! :) – Bailey M May 7 '15 at 12:57

You are

tantalum, number 73 in the periodic table.

Add to me one and I'll become a mess;

Tungsten, number 74, is somewhat toxic.
