NGSS.HS-PS1-1

A chemical bond where electrons are shared between two atoms. In this type of bond no ions are. You will find these bonds when carbon bonds to other elements.

• Covalent bond

NGSS.MS-PS1-1

A physical model that depicts the atom as a small positively charged nucleus with electrons in orbit at different levels.

• Covalent bond

• Ionic bond

• Bohr Model

• Electron dot diagram

A chemical bond between two atoms where one or more electrons are passed from one atom to another. When they give up electrons, each of the atoms should have a filled shell. An example is the sodium chloride bond.

What is one way Neutrons are different from electrons?

• they both are negative

• neutrons have no charge, while electrons have a negative charge

• Both are in the nucleus( center of atom)

• Electrons are inside nucleus and neutrons are outside the nucleus.
