How do you determine how many PROTONS are in an atom Correct Answer The atomic number
How do you determine how many NEUTRONS are in an atom Correct Answer Take the atomic mass and subtract it from the atomic number. They are also equal to the number of protons in a neutral atom
How do you determine how many ELECTRONS are in an atom Correct Answer They are equal to the number of protons in a neutral atom
What are the most common atoms found in a cell Correct Answer Carbon
Hydrogen
Nitrogen
Oxygen
Phosphorus
Sulfur
What is an ion Correct Answer When protons and electrons are not equal, causing a charge (either positive or negative and will be indicated/given by a coefficient next to the chemical symbol)
What is an atom Correct Answer An electrically neutral element (balanced number of protons and electrons), these are the smallest forms of life
What are isotopes Correct Answer Same elements with different atomic masses (due to an increased number of neutrons in the nucleus)
Why do atoms bond with each other Correct Answer In order to fill their valence shells in order to become more stable
How do you determine the type of bond two atoms share Correct Answer Find the electro negativities of each element, then subtract the smallest number from the largest
What is a covalent bond Correct Answer Occur when the electro negativity difference is between 0-1.7 and is between two NON-METAL elements.
- These type of bonds can have up to triple bond, these bonds are the most common in this class
What is an ionic bond Correct Answer Occurs when the difference of electro negativity is greater than 1.7. The transfer from a less electronegative to a more electronegative atom.
