At what organizational level is life's uniformity most evident? Most evident in cells At what organizational level is life diversity most evident? Most evident in organisms How do Atoms fill their Valence shell? Donate or accept electrons from another atom or two atoms can share an electron pair creating a covalent bond. What happens when an atom gains or loses an electron? It becomes ionic 96% of living mater is composed of which elements? Carbon, Nitrogen, Hydrogen, Oxygen (HONC) How c...

The structure of a strand of DNA. - Answer-it is a double helix, like a twisted ladder. the ladder rings are nucleotide subunits and they have a covalent bond to the sugar phosphate backbone (made of deoxyribose and a phosphate group) What are the nucleotide subunits? - Answer-adenine, guanine, cytosine, and thymine How are the subunits held together? - Answer-through a hydrogen bond What are the nucleotide subunits compliments? - Answer-Adenine and thymine cytosine and guanine How does D...

Phosphorus has an atomic number of 15. This tells us that... - Answer-there must be 15 protons True or False: covalent bonds are stronger than ionic and hydrogen bonds because atoms that are joined with covalent bonds share electrons - Answer-True An e- in a hydrogen atom exists in the first valence shell. The valence e- of Aluminum exist in the 3rd shell. Which valence shell e- have higher potential energy and why? - Answer-the valence e- of aluminum, bc higher e- shells have higher energy...

chemical bond CORRECT ANSWER the force that holds two atoms together Atoms gain stability when CORRECT ANSWER they share electrons and form covalent bonds. The stability of an atom, ion or compound is related to its energy: CORRECT ANSWER lower energy states are more stable Metals and nonmetals gain stability by CORRECT ANSWER transferring electrons (gaining or losing) to form ions that have stable noble-gas electron configurations. Another way atoms can gain stability is CORRECT ANS...
