ical bonding patterns of atoms. Linear Geometry **Electron Arrangement:** Two regions of electron density **Examples:** BeCl₂, CO₂ **Characteristics:** Atoms are arranged in a straight line with a bond angle of 180°
cules like water have a bent shape instead of linear? Water has two lone pairs on the oxygen atom, which repel bonded pairs and result in a bent shape with a bond angle of about 104.5 degrees. What shape does methane (CH₄) exhibit in covalent molecule shape labs? Methane exhibits a tetr
