The periodic table
What's the periodic table?
Arrangement of chemical elements depending on their functions on characteristics.
Organized in families and periods
Name 3 periodic table families
Any of these:
Alkali metals
Alkaline earth metals
Transition metals
Boron Group or Earth metals
Carbon Group or Tetrels
Nitrogen group
Oxygen group
Halogens
Noble Gases
When can something be considered "organic"?
Involved in life processes and has Carbon and Hydrogen as part of its structure
Symbol for Carbon
C
What are biomolecules?
Biomolecules are chemical compounds found in living organisms. They are the building blocks of life, essential for the functioning of living organisms.
What's a valence electron?
Electrons in the outermost shell of an atom, and that can participate in the formation of a chemical bond
Name 2 noble gases and their symbol
Any of these:
3 examples of organic matter
How many valence electrons does Carbon have?
4
Carbohydrates, proteins, lipids, nucleic acids
What's atomic weight?
The mass or weight of an atom
Name 3 metals and their symbols
Any of these:
3 example of inorganic matter
What can carbon do with its valence electrons?
Each carbon atom can form up to four bonds with other atoms, enabling it to create a vast array of simple and complex molecular structures.
Main elements in Biomolecules
C, H, O, N, P, S
Name 5 elements and their symbols
Which periodic table family is the most reactive?
Alkali metals and halogens
How do fossil fuels form from organic matter?
Fossil fuels form from the buried remains of ancient plants and animals, subjected to heat and pressure over millions of years.
Why is carbon the element that forms the foundation of life?
Each carbon atom can form up to four bonds with other atoms, enabling it to create a vast array of simple and complex molecular structures.
Carbon can be found in a wide range of compounds, from the atmospheric gas carbon dioxide to the hard, crystalline structure of diamonds and the soft, flaky graphite.
The versatility of carbon's bonding allows it to form a diverse array of molecules, from small, simple structures to large, intricate ones, making it a fundamental building block of life.
Structural, storage, transport, cellular communication
Atomic number definition
Number of protons (and therefore of electrons) of an atom
In what group is flourine found?
Halogens
"Chemical name" for salt
Sodium Chloride (NaCl)
Cloruro de sodio
Brief description of the carbon cycle
The carbon cycle is the continuous movement of carbon between the atmosphere, oceans, land, and living organisms. This natural circulation maintains a delicate balance, regulating the climate and sustaining soil fertility essential for life. Carbon is continuously exchanged and recycled through various processes, ensuring a vital equilibrium on our planet.
What does DNA stand for?
Deoxyribonucleic acid
Ácido desoxirribonucleico
