Chem 4- Electrons

Wendy Riggs2 minutes read

Electrons determine the charge of an atom by orbiting the nucleus, while changing protons alters the element. Ions, formed by adding or subtracting electrons, play a crucial role in physiological functions and chemical bonding.

Insights

  • The charge of an atom is determined by the balance of positive protons in the nucleus and negative electrons orbiting it, with changing the number of protons altering the charge and element, while changing electrons only affects the charge.
  • Ions play a crucial role in physiological functions, particularly in the nervous system, by facilitating electrical impulses, emphasizing the significance of electron behavior in creating these charged particles essential for various biological processes.

  • Adding electrons creates a negative ion, subtracting them results in a positive ion.
  • Ions are crucial in physiological functions, especially in the nervous system where they facilitate electrical impulses.
  • Electrons are essential for chemical bonds, where atoms share electrons to form molecules.
  • Chemical bonds can be covalent (equal sharing), ionic (one atom takes all electrons), or polar covalent (unequal sharing).
