According to APE MAN, in a neutral atom, the atomic number equals

• the mass
• # protons PLUS # neutrons
• # neutrons and # protons
• # protons and # electrons

Elements in the same period have the same - 

• # valence electrons
• atomic #
• # energy levels
• mass #

Elements in the same group have the same - 

• # valence electrons
• atomic #
• mass #
• # energy levels

What element has 16 protons?

• Se
• S
• P
• Ca

As you go across a period, the - 

• atomic # increases
• valence # decreases
• # energy levels increase
• atomic mass decreases
