In this case there are a few different periodic trends at XXXX. XX you XXXX at the periodic table, moving down a row will add a shell to XXX XXXX (getting XXXXXX). XXXXXXX, moving XX XXX right means the atom is XXXXXXX smaller. When you XXXX to XXX XXXXX, in a row, XXX nucleus XXXX more and XXXX XXXXXXXX, XXXXXXX XXX XXXXX ofelectrons closer XX XXX middle (XXXXXXX XXXXXXX). XX even XXXXXX the atom XX getting more XXXXXX in it, the XXXX itself XX getting smaller XXXXX XXX XXXX tightly XXXXX.
When dealing with charges, XXXXX can act XXXXXXX. XX this case, XXX of XXX atoms have XXX same number XX XXXXXXXXXXXXXX. Look on the table and XXXX spaces depending on the XXXXXX. (XXXX XXX XXXX XXX XXXX number of electrons as XX ).
XXXX XXX size XXXXXXX on how XXX protons act and XXX XXXX with XXXX protons XXXX be XXXXXXX as XXX electrons XXX more XXXXXXX bound.
XXXX: The attached XXXXX XXXXX the sizes for XXXXX that XXXX't XXXX. For ions, consider XXX XXXXX XXXXX.
