Water lower resistance? Our body, excluding skin, is not very resistant because blood and other bodily fluids have high ion concentrations which allow current to flow quite easily. When water comes in contact with skin, the resistivity of the skin is decreased because most water already has sufficient ions to conduct electricity.

Chemical Bonding This is an unstable state because that valence shell needs eight electrons to be full. In order to fill its valence shell, sodium has two options: 1  Find a way to add seven electrons to its valence shell, or.  Give up that one electron so the next lower energy shell (already full) could become its new valence shell.

What happens if you drink too much water? Also known as water poisoning, water intoxication is the disruption of brain function due to drinking too much water . Drinking a lot of water increases the amount of water in your blood. This water can dilute the electrolytes in your blood, especially sodium. When sodium levels fall below 135 mmol/L, it is called hyponatremia.

The Sodium/Chlorine Reaction They combine as atoms, and separate as ions. When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. The sodium (Na) atom transfers one electron to the chlorine (Cl) atom, so that they both have full outer shells.With filled outer shells they are no longer chemically active and can't form covalent bonds to become part of a molecule.ecause the sodium ion has a positive charge, and the chlorine ion has a negative charge, they are attracted to each other, and form an ionic bond. Ions form salts, not molecules, but they perform many important functions in nutrition.

Medical Dangers of Too Much Sodium Since sodium attracts water, your body also uses it to regulate the amount of fluid in your blood, organs and tissues. When your body contains too much sodium, your kidneys remove it by producing more urine. However, if you consume large amounts of sodium, you kidneys might not be able to handle all the excess, allowing too much sodium to remain in your body.

- Sodium reacts with chlorine to form Na + ions and Cl-ions in spite of the fact that the first ionization energy of sodium is larger than the electron affinity of chlorine. An electron is then added to each chlorine atom to form a Cl-ion. 2  This is the first exothermic step in this process, and the energy released is equal to the electron affinity of chlorine.

- 1 When it is mixed with water or an acid, sodium azide changes rapidly to a toxic gas with a pungent (sharp) odor. 2  It also changes into a toxic gas (hydrazoic acid) when it comes in contact with solid metals (for example, when it is poured into a drain pipe containing lead or copper). Breathing the gas that is formed from sodium azide causes the most harm, but ingesting (swallowing) sodium azide can be toxic as well. 2  The gas formed from sodium azide is most dangerous in enclosed places where the gas will be trapped. 3  The toxic gas quickly disperses in open spaces, making it less harmful outdoors.

- The reaction releases heat, and as the sodium and the solution warm up, the reaction goes faster and faster. If the sodium gets trapped on the water's edge or against some other obstacle, enough heat can be generated to boil the water around the metal and actually melt the sodium. This is a dangerous reaction. If the sodium gets hot enough, the hydrogen jets can ignite and burn.
