Why does this model show that this Beryllium atom is a positive ion?

• It has more electrons than protons
• It has more protons than electrons
• It has less neutrons than electrons
• It has less neutrons than electrons or protons

How would the electron configuration change for the Beryllium ion above?

• It would not change because it is the same element.
• It would have two extra electrons and look like Carbon.
• It would have two fewer electrons and look like Helium.
• It would have two extra protons and look like Carbon.
