Titanium has an atomic number of 22. Therefore it has 22 protons, and the number of electrons is the same.
Since the isotope's mass number is 49, there are 49 - 22 neutrons = 27.
It's hard to draw the symbol here, but it's more or less like this:
49
Ti
22
...except the numbers would be closer together
