Use the periodic table and complete the following information todetermine the number of protons, neutrons and electrons andto know the identity of an atom

The atomic number of an atom is the number of:Protons plus electronsNeutronsProtonsProtons plus neutrons3The relative atomic mass of an atom is the number of:Protons plus electronsProtons plus neutronsProtonsNeutrons4Referring to the periodic table, calculate how many neutrons are found in sodium (Na):23011125An atom has 12 electrons. Use the periodic table to identify the chemical symbol for this atom:CMgKO

How is the atomic mass of an element determined?By adding the number of protons and electronsBy the number of protons in the nucleusBy the number of electrons in the outer orbitalsBy adding the number of protons and neutrons in the nucleus

Continue adding protons until there are six protons in the nucleus.Record the information provided at each step to complete the table.ElementNumber of protons in nucleusAtomic numberhydrogen12lithium344boron6
