wHAT IS THE SYMBOL FOR THE ION WITH 13 PROTONS AND TEN ELECTRONS?
CAN U EXPLAIN HOW TO GET YOUR ANSWER, AND CAN YOU GIVE ME A WEBSITE THAT HELPS ME WITH CHEMISTRY


13 protons will be element with atomic number of 13. Look on the periodic table and see atomic number 13 is aluminum. The symbol is Al. Al normally has 13 electrons. If three of them are not there, then the charge on the Al will be 3+. So the symbol for the ion is Al^3+. As for a site that can help you, this is a great site and we welcome questions but we want to hear your input too. For other questions about the periodic table, a good site is www.webelements.com
