Basic chemistry & The Periodic Table
Residing in the nucleus of an atom, this subatomic particle is positively charged.
What is a proton?
These types of waves travel at the speed of light.
What are electromagnetic waves?
What are greenhouse gases?
An electron in the outer shell of an atom that can form chemical bonds with other atoms.
What is a valence electron?
This pigment comes in two forms and can protect the skin from UV damage by absorbing UV photons.
What is melanin?
This property of a substance can be observed without changing the substance into something else.
What is a physical property?
This layer of our atmosphere is responsible for absorbing a large amount of UV radiation.
What is the ozone layer?
This natural formation is used in combination with spectroscopy techniques to measure the composition of Earth's atmosphere many millennia in the past.
What are ice cores?
This type of bond is formed when electrons from different atoms are shared.
What are covalent bonds?
What is carbon monoxide?
This atomic property is determined by adding the number of protons and neutrons together.
What is atomic mass?
This type of electromagnetic radiation cannot be seen by humans but can be felt as heat.
What is infrared radiation?
This type of radiative forcing exerts a cooling effect.
What are negative forcings?
This value increases up and to the right of the periodic table, and is a measure of how much an atom attracts electrons in any given chemical bond.
What is electronegativity?
This value is determined by the concentration of H+ ions in a solution.
What is pH?
This group of the periodic table primarily contains highly reactive metals, with the exception of hydrogen, and occupies the leftmost column of the periodic table.
What are alkali metals?
This type of sunscreen protects the skin from UV rays by reflecting the rays and blocking them from reaching skin cells.
What is mineral sunscreen?
What are phenological changes?
This intermolecular force contributes majorly to water's unique properties, and is formed as a result of partial positive and partial negative charges between polar covalent bonds.
What are hydrogen bonds?
First synthesized in the 1930s and later banned, these compounds are responsible for depletion of the ozone layer.
What are chlorofluorocarbons?
