What is the maxim number of each electron shell?
2,8 8 2
How many shells can there be in an atom?
As many as possible
What shell contains the electrons with the lowest energy
The one closest to the nucleus
what can extra energy added to an electron shell cause?
It can cause it to jump to a higher leave causing it to become exited
What is the excited state of an atom?
It is when a valence electron absorbs energy
what is the atoms ground state?
It is the lowest possible energy state
What is an Ion
It is when an atoms as more or less electrons than protons
what are postive ions
It’s when there are more protons then electrons in the atom
What is the name given to the different energy levels that electrons can be found in?
Electron shells
How many electrons are needed to fill the first shell
2
How many electrons are needed to fill the second shell
8
how is an ion formed
When an atom loses or gains a electron
What does the nuclear symbol ‘Z’ stand for
An atom’s atomic number is represented by the letter Z. In other words, Z stands for how many protons it has.
