Which of the following does not divide $n^{2225}-n^{2005}$ for every integer value of $n$?

$ 
\textbf{(A)}\ 3
\qquad\textbf{(B)}\ 5
\qquad\textbf{(C)}\ 7
\qquad\textbf{(D)}\ 11
\qquad\textbf{(E)}\ 23
$
1. We start with the expression \( n^{2225} - n^{2005} \). We can factor this as:
   \[
   n^{2225} - n^{2005} = n^{2005}(n^{220} - 1)
   \]
   This factorization helps us analyze the divisibility properties of the expression.

2. To determine which of the given numbers does not divide \( n^{2225} - n^{2005} \) for every integer \( n \), we need to consider the Euler's Totient Function, \(\phi\), for each of the numbers. Euler's Totient Function \(\phi(m)\) gives the count of integers up to \( m \) that are coprime with \( m \).

3. We calculate \(\phi\) for each of the given numbers:
   - \(\phi(3) = 2\)
   - \(\phi(5) = 4\)
   - \(\phi(7) = 6\)
   - \(\phi(11) = 10\)
   - \(\phi(23) = 22\)

4. For a number \( m \) to divide \( n^{220} - 1 \) for every integer \( n \), \( 220 \) must be a multiple of \(\phi(m)\). This is because \( n^{\phi(m)} \equiv 1 \pmod{m} \) for any integer \( n \) that is coprime with \( m \) (Euler's Theorem).

5. We check the divisibility of \( 220 \) by each \(\phi(m)\):
   - \( 220 \div 2 = 110 \) (integer, so \( 2 \mid 220 \))
   - \( 220 \div 4 = 55 \) (integer, so \( 4 \mid 220 \))
   - \( 220 \div 6 = 36.6667 \) (not an integer, so \( 6 \nmid 220 \))
   - \( 220 \div 10 = 22 \) (integer, so \( 10 \mid 220 \))
   - \( 220 \div 22 = 10 \) (integer, so \( 22 \mid 220 \))

6. From the above calculations, we see that \( 220 \) is not divisible by \( 6 \), which is \(\phi(7)\). Therefore, \( 7 \) does not divide \( n^{2225} - n^{2005} \) for every integer \( n \).

Conclusion:
\[
\boxed{7}
\]
