Electron Shells + Diagrams of Atomic Structure

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

• Proton

• Atom

Which of these have a neutral energy?

• Atomic Shell

• Electron

• Proton

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.
