Why are atoms neutral if there are protons and electrons? The number of protons and electrons are the same.
How come you cannot transfer protons to make an ion? Protons are in the nucleus, while electrons move because they are found on orbitals surrounding the nucleus.
What is the maximum amount of electrons on the first, second, and third orbitals? first shell: 2second shell: 8third shell: 8
How many electrons does the boron family have? It has 3 valence electrons.
Is the atom the smallest particle ever? No.
If you move down a column in the periodic table, what do you notice about the shells? They increase by one each time you move down.
Name three properties for halogens. 1. poisonous2. very reactive3. can all form gases
What are the 3 things an element can be classified as in the periodic table? Metals, non-metals, and metalloids
If sulfur is in the oxygen family (6 valence electrons) and it is the second element in the column, how many protons does sulphur have? Sulphur has 16 protons.
