It's because your font-style:italic takes extra space.

You can add some fixed width to the li.

#menu #nav {
  font-family: Segoe UI, Arial, sans-serif;
  font-size: 14px;
  color: #000;
  list-style: none;
}

#menu #nav li {
  display: inline-block;
  padding: 0px 10px 0px 10px;
  width: 50px;
}

#menu #nav li a {
  font-family: Segoe UI, Arial, sans-serif;
  font-size: 14px;
  color: #000;
  text-decoration: none;
}

#menu #nav li a:hover {
  color: #0a813c;
  font-style: italic;
}

<div id="menu">
  <ul id="nav">
    <li><a href="index.php">Pagrindinis</a></li>
    <li><a href="#">Taisyklės</a></li>
    <li><a href="#">Pamokos</a></li>
    <li><a href="#">Kontaktai</a></li>
    <li><a href="#">Facebook</a></li>
  </ul>
</div>
