2/1/12If theres an atomic number of 11, the atomic nucleus has 11 protons, so the 3rd shell only has 1 electron (due to the amount of electrons each shell can hold)For the atom with atomic number 11, the one in the 3rd shell is donated, leaving a full 2nd and 1st shell. With the loss of the electron, the atom becomes an ion, or a charged particle. Because the ion is positively charged, it is a cation. Sodium has an atomic number of 11Atom with atomic number 10- 10 protons, 10 electronsThis atom is not reactive because its outermost shell is complete, the atom is stableReactive atoms have valence shells that are not complete. Such atoms are involved in chemical reactions to obtain or achieve stability. Stability is the basis of chemical reactions Atomic number 17- ChlorineThere are 7 electrons in the 3rd shell. By the octet rule, it needs just one more electron to achieve stability and become and chloride ion.It will gain an electron, become negatively charged and an anionAtomic number 6- CarbonCarbon will share electrons with other atoms to achieve stability so many relationships can occur.Based on the reactivity of atoms in the body, we’ll be looking at 3 types of chemical bonds in the human body-covalent bonds- atoms share electrons equally to achieve stability -polar covalent bonds- unequal sharing of electrons (ex. Water)based on chemical reactions occurring in the human body, we know there are 2 types of compounds, organic and inorganic. Organic contains chains of carbon, carbons are covalently linked, inorganic does not contain carbon chains. Inorganic compounds in the human body: water- a polar covalent compound. A universal solvent. All biochemical reactions occurring in the cells require or produce water, could be a hydration or dehydration reactionwater in blood absorbs heat to maintain core body temperature- has a high heat capacity. Blood is slightly warmer than the core body temperature. Maintenance of thecore body temperature is necessary for enzymatic actions to promote the biochemical reactions occurring in the body.Water has a high heat of vaporizationBecause of the increase in the core body temperature, the body will sweat, the vaporization of water from the surface of the skin requires an increased temperature. This results in a decrease of CORE body temperature “cooling”, the energy is going elsewhere so the core body temp is
