Why do elements from group 1 and group 7 react so well |
Because the electrons from group 1 are being given to the shell of the element from group 8 therefore creating a full shell leaving the element from group 1 without any. |

Protons and electrons charges |
Protons and electron have electrical charges. The charges are the same size for both but protons are positive and elections are negative. |

Metal reactions |
When a metal reacts with a non-metal, each metal atom loses the electron, or electrons, from its outer shell. The atom loses negative electrons but still has the same number of positive protons, so it has an overall positive charge. It's not an atom now. Instead it is called an ion. |
