Which of the following explains the location of nitrogen the periodic table?
It has one more proton than carbon, so it is located after carbon, and it is a metal, so it is located on the right of the periodic table.
It has one less proton than carbon, so it is located after carbon, and it is a non-metal, so it is located on the right side of the periodic table.
It has one more proton than carbon, so it is located after carbon, and it is a non-metal, so it is located on the right side of the periodic table.
It has one less proton than carbon, so it is located after carbon, and it is a metal, so it is located on the right side of the periodic table.

William drew a model of the atom beryllium(Be). In the nucleus he included 4 protons and 4 electrons. Orbiting the nucleus he added 5 neutrons in the shells. What mistake did he make?
The protons should be circling the nucleus, not the neutrons.
The neutrons should be in the nucleus with the protons and the electrons should be in the shell.
The nucleus should have electrons and neutrons, not protons and electrons.
