The main-group elements are the forty-four elements that occupy groups 1A-VIIIA of the periodic table. Main-group elements are important because of their high natural abundance both in the Earth's crust and in the human body and are commercially valuable
Review the families containing main group elements and locate families IVA - VIIA. When forming chemical compounds, these four
families have commonalities. Explain using as many answer choices that would apply.

What happens to isotopes that are unstable?

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?

Acompound has the molecular formula c3h8. which class of organic compounds does it belong to?
