1.) Define: What are ions?
An atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
2.) Explain what are cations and how do they form?
A cation is an ion as well, but it is positively charged- an atom that has lost 1+ electrons. They form when an atom that is neutral loses more electrons.
3.) Explain what are anions and how do they form?
Anions are also ions, but they are positively charged. They form when a neutral atom gains electrons, this typically happens when it's a nonmetal.
2.) Describe: what are valence electrons?
Valence electrons are in the outermost shell of an atom, and participate in the forming of a chemical bond.
3.) What are the shortcuts on the periodic table to knowing how many valence electrons an element has?
Elements in group 1 have 1 valence electron, and elements in group 2 have 2 valence electrons. For elements in groups 13-18, the number of valence electrons is equal to the group number minus 10.
4.) What is the role of the electron in energy absorption and emission?
Electrons absorb energy by jumping to higher energy levels and emit energy by falling to lower energy levels. This energy is released or absorbed in the form of photons, which are particles of light.
1.) Explain: What are electrolytes and why are they important for humans? (2-4 sentences)
Electrolytes are electrically charged minerals that help regulate various bodily functions. Such as: nerves and muscle function. They are essential for maintaining proper hydration and enabling our bodies to function correctly. They also help regulate the balance of fluids within our cells.
2.) What could happen if we don't receive enough electrolytes? And if we have too many electrolytes?
If we don't receive enough electrolytes, we may experience muscle cramps, weakness, and fatigue. Worst case scenario, this can result in death. Having too much electrolytes can cause swelling, bloating, discomfort for your stomach. Too little can also cause cardiac arrest, and seizures etc...
