Question

17. A charged atom or molecule is called: 18. Adjacent water molecules are held together by this type of bond. 19. An atom that gains an electron is called: 20. An atom that gains neutrons is called: 21. An element is determined by the number of these sub-atomic particles. In this type of bond, electrons in the outermost shell are shared by two atoms. In this type of bond, one atom lost electron(s) and the other atom gained electron(s). Then, the oppositely charged atoms or molecules are attrcted to each other. 22. 23. 24. In this type of molecule, there is a positively charged region and a negatively charged region because the electrons are not shared equally. (Note there is a positive pole and a negative pole). Molecules that are insoluble in water (separate from water and don't dissolve) are called: 25. 26. On the pH scale, the higher the number, the morethe substance. 27. The amount of a dissolved solute in a certain amount of solvent is 28. The atomic mass is based on the number of these sub-atomic 29. The concentration of hydrogen ions (H') in solution is referred to as 30. These sub-atomic particles are involved in interactions of two or called the solution's particles. the solution's: more atoms.
