Worksheet time: 8mins
What is an Electron Shell?
Outermost shell and it determines bonding.
The Electron Shells is the outside part of an atom around the atomic nucleus.
Contains electrons, the number of electrons per shell corresponds to the number of atoms in that row of the periodic table.
How are electron placed in a shell?
Shells furthest away from the nucleus will hold the electrons with the highest level of energy.
Atoms with outer electron shells that are not full are less stable.
The first shell holds 2 electrons, and subsequent shells can hold up to 8 electrons.
Shells closest to the nucleus will hold electrons with the lower levels of energy.
True
False
What are Subshells?
Subshells contain three dumbbell-shaped orbitals at right angles to each other.
Are shells from the ocean. Yes ma'am.
Means something invisible and cannot be cutted or divided.
How do electrons store and release energy?
They get connected to a energy current and this is how they store energy.
The Electron Shells is the outside part of an atom around the atomic nucleus.
They have a box in which energy is stored and when it is opened, it releases everything inside.
Electrons can jump from a lower-energy shell to a higher-energy shell when excited by energy such as heat.
Which of these have a negative energy?
Proton
Electron
Neutron
Which of these have a positive energy?
Electron
Neutron
Proton
Atom
Which of these have a neutral energy?
Atomic Shell
Electron
Proton
Neutron
What is an Atom?
Not fully completed are less stable and will react with other atoms.
It is something invisible and so small it cannot be cutted or divided.
Completely full are stable and will not react with other atoms.
What is an Atomic Structure?
It is the outside part of an atom around the atomic nucleus.
Have one or more electron subshells, or sublevels.
Is the positively charged nucleus surrounded and neutralized by the negatively charged electrons orbiting around an atom.
