TEAS ATI 7 Exam Questions and Answers 100% Pass How many valence electrons does an atom have if the atom has an atomic number of 10? -Answer-8 valence e- because it ends with 2s2 2p6 How many valence electrons will an atom have if the atom is located in Group VIA of the periodic table? -Answer-VI=6 An atom located in which of the following groups on the periodic table of elements will most likely gain electrons from another atom in a chemical reaction? -Answer-The higher the valence electrons, the most likely it'll want to gain- so it can be full. Which of the following parts of an atom gives the atom its reactivity? -Answer-Electrons How many electrons can the S orbital hold? -Answer-2 electrons How many electrons are in the p orbital of Oxygen if Oxygen has a total of 8 electrons? -Answer-1s2 2s2 2p4 = 4 p orbitals If Neon has an atomic number of 10 and a mass of 20, how many valence electrons does Neon have? -Answer-1s2 2s2 2p6= 8 valence e- What will most likely occur to an element that has a low ionization and a low electronegativity? -Answer-It will form a cation What atom has the highest electronegativity? -Answer-Fluorine Where would the largest atomic radii occur in the periodic table of elements? -Answer- Bottom left What does electronegativity mean? -Answer-Measurement of how strongly an atom attracts electrons If an atom has a low ionization energy, does an require high or low energy to remove an electron from an atom? -Answer-Low energy Which of the following types of bonds will occur between two atoms that have a large difference in their electronegatives? -Answer-Ionic Bonds In which of the following scenarios would two atoms most likely form a covalent bond? - Answer-A covalent bond will form between two atoms that have similar electronegativite What is the charge of an atom that is located in Group IIIA of the periodic table of elements? -Answer-+3 charge A double covalent bond between 2 atoms indicates? -Answer-Two atoms share two pairs of electrons What bond type are electrons lost or gained between atoms of two ionic bonds? - Answer-Ionic Bond A negatively charged ion is also called? -Answer-An anion What phase change happens in Sublimation? -Answer-Solid to gas, ex: dry ice What phase change happens in deposition? -Answer-Gas to solid What does triple point mean? -Answer-Temperature and pressure where the substance is solid, liquid, and gas at the same time What does critical point mean? -Answer-Liquid and gas coexist together The universal solvent is? -Answer-Water What is composed of one glycerol and three fatty acids? -Answer-Triglycerides What structure is mainly composed of phospholipids? -Answer-Cell membrane Steroid hormones are classified as? -Answer-Lipids What happens during Dehydration Synthesis? -Answer-When amino acids link together to build a protein What monomer is used to build proteins? -Answer-Amino Acids What class of macromolecules has the most diverse functions? -Answer-Proteins What chemical group is not found in the basic structure of every amino acid? -Answer- Phosphate Group What chemical group in an amino acid always contains Nitrogen? -Answer-Amino group What monomer is used to build enzymes? -Answer-Amino Acids What does activation energy mean? -Answer-Energy required to start a chemical reaction Do enzymes reduce or increase activation energy? -Answer-reduce What macromolecule stores genetic information? -Answer-Nucleic Acids In DNA molecules which nucleotide pairs with Adenine? -Answer-Thymine In RNA molecules which nucleotide pairs with Guanine? -Answer-Cytosine What organelle would be involved if a non-functioning protein us accidentally produced by the cell? -Answer-Lysosomes because they're responsible for breaking down nonfunctioning lysosomes
