## What is VSEPR Chemistry Invaders?

VSEPR invaders in an arcade-style shooter app that helps students learn the various molecular geometries as a result of electron repulsion. 

First, users learn various different VSEPR configurations. These include:

Linear, Trigonal Planar, Tetrahedral, Trigonal Bipyramidal, and Octahedral. 

Next, the user starts the game and has a certain amount of time to shoot as many geometry models as possible. 

Each ten-second segment of the game selects a certain molecular geometry and the student must target these models in order to score five points. 

If the user shoots the incorrect model during the ten second period, they lose 1 point. 

Once, the timer has reached ninety seconds, the game stops and the user's score is reported.

This app provides a fun and interactive experience to help learn molecular geometry in an innovative and new manner.

The free version of the app features games that last 1 to 2 minutes and the In-App purchase provides extended game length from 3 to 8 minutes.
