Presentation transcript:

Atoms: Independent Practice (INB 46) Each element is made of groups of a single type of atom. Atoms are made of _____, _______ and _____ which are subatomic particles. The atomic number is the number of protons in the nucleus. Every element has a certain number of protons in its nucleus. The number of protons is element’s unique fingerprint- unique identity.

Nucleus Central part of the atom Contains most of atom’s ______ (extremely dense) _______ move rapidly around it Made of protons and ________ It is positively charged as it contains a proton (+ charge) and a neutron (0 charge).

On the bottom of page 46 Write what the atomic # is and the atomic mass # is after drawing this. Using your textbook, turn to page 78 and draw the model of an atom. Homework: Review Notes and complete drawing
