Add up the sum of protons and neutrons Chem, 100 The three particles that make up the atom are… Protons, Neutrons, and Electrons Atoms, 100 This type of bond is when electrons are transferred to another atom. Ionic bond Bonding, 100 What are the 4 biomolecules? Carbs, Proteins, Lipids, Nucleic Acids Biochem, 100 An atom that has gained or lost neutrons is called… An isotope Chem, 200 If an atom has 3 protons, 4 neutrons, and 3 electrons the atomic mass is… 7 Atoms, 200 Carbon can form how many covalent bonds? 4 Bonding, 200 A single unit in a biomolecule is called… A monomer Biochem, 200 What are valence electrons? Outermost electrons Available to bond Chem, 300 What is the atomic number of an element with 8 protons, 9 neutrons and 8 electrons? Atomic number 8 Oxygen Atoms, 300 This is what is formed when you have the covalent joining of two or more elements? Molecule Bonding, 300 A molecule is considered organic if it contains… Carbon Biochem, 300 What is the difference between an ionic and covalent bond? Ionic: electrons transferred Covalent: electrons shared Chem, 400 Atoms of the same element with the same number of protons, but different number of electrons is called… Ion Atoms, 400 If an atom loses an electrons its charge becomes… Positive Bonding, 400 Meats and beans are high in which biomolecule? Protein Biochem, 400 Put the bonds in order from strongest to weakest. Covalent, hydrogen, ionic Covalent Ionic Hydrogen Chem, 500 If an atom has 17 protons, 17 neutrons, and 18 electrons, the net charge of the atom is… -1 Atoms, 500 Explain the steps to form NaCl. First there needs to be an ionization where Na loses an electron and transfers it to Cl. Next, the charged ions form an ionic bond. Bonding, 500 The biomolecule that is not typically found in food is… Nucleic acids Water, 500
