Hi there
Can someone please show me how to draw a fully labelled diagram of atoms such as:
He ( the proton number at the top is 4 and the atomic mass at the bottom is 2)
I now that it would have protons and neutrons in it and the electrons would be outside
But how many shells would I draw and what wolud it look like?
Thanks I really appreciate

To draw a fully labeled diagram of an atom like helium (He) with a proton number of 2 and an atomic mass of 4, you would follow these steps:
1. Start by drawing the atomic symbol for helium, which is "He."
2. Write the proton number (atomic number) at the top of the symbol, which is 2. This indicates the number of protons in the helium atom.
3. Write the atomic mass at the bottom of the symbol, which is 4. The atomic mass represents the sum of the protons and neutrons in the atom.
4. Draw the nucleus in the center of the symbol. The nucleus contains the protons and neutrons. Since the atomic mass is 4, you would have 2 protons and 2 neutrons in the nucleus.
5. Draw two electron shells around the nucleus. The first shell, closest to the nucleus, can hold a maximum of 2 electrons. Place the first 2 electrons in this shell.
6. The second shell can also hold a maximum of 2 electrons. Place the remaining 2 electrons in this shell.
Remember that electrons are arranged in shells or energy levels around the nucleus. Each shell can only hold a specific number of electrons. The innermost shell (closest to the nucleus) can hold a maximum of 2 electrons, while the second shell can also hold 2 electrons.
To get a visual representation of a fully labeled helium atom, you can search on Google Images using the link you provided: http://images.google.com/images?svnum=10&um=1&hl=en&lr=&q=helium+atom
