Across
- 3. A positively charged subatomic particle that is located in the nucleus of an atom
- 5. a physically distinctive form of matter( such as a solid, liquid, gas, or plasma) and is characterized by having relatively uniform chemical and physical properties
- 7. an atom that has lost electrons, giving it a positive charge
- 8. A negatively charged ion
- 13. the arrangement of electrons in energy levels around an atomic nucleus
- 15. a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds(this can be an ionic bond or a covalent bond)
- 16. also called a group, is a column of elements in the periodic table of elements
- 19. a notation used by scientists to show the number and type of atoms present in a molecule, using the atomic symbols and numerical subscripts
- 22. A positively charged ion
- 24. A negatively charges subatomic located in the electron- cloud
- 25. a type of linkage formed from the electrostatic attraction between oppositely charged ions in a physical compound, this bond forms when the valence electrons of an atom are permanently transferred to another atom
- 27. The core of an atom
- 30. a group of atoms bonded together, showing the smallest fundamental unit of a chemical compound that may take part in a chemical reaction
- 31. a substance when two or more chemical elements are chemically bonded together, there are two common types of bonds holding elements together in a compound which are covalent and ionic
- 32. an atom that has gained electrons, giving it a negative ions
- 33. outer shell electrons of the atom that determine an atom’s or group’s ability to bond with others
- 34. Specific patterns in the properties of chemical elements
- 35. a substance composed of exactly two different elements, in which the substances can’t be simplified further by chemical means
- 36. number-The total number of protons and neutrons, which are located in the nucleus
Down
- 1. a distinguishing symbol, such as a letter or numeral, written below or below to the right/left of another character
- 2. the interatomic linkage that comes from the sharing of an electron pair between two atoms, in which the binding arises from the electrostatic attraction of their nuclei for the same electrons
- 4. the vertical columns of the periodic table
- 6. mass- The total mass of an atom
- 9. atoms of an element with the same number of protons & electrons, but a different number of newtons
- 10. a chemical element that lacks the characteristics of a metal and tends to have a relatively low metal point, boiling point and density
- 11. number- The total number of protons of an atom
- 12. a compound composed of ions of two different elements, one a metal and another a nonmetal
- 14. the horizontal rows of the periodic table
- 17. A neutral charged subatomic particle located in the nucleus
- 18. cloud- The area/region of electrons surrounding the nucleus in an atom
- 20. An atom that has an electrical charge
- 21. The smallest unit of matter
- 23. a chemical element that forms a simple substance and has properties intermediate to typical metals and nonmetals
- 26. outer shell electrons of the atom that determine an atom’s or group’s ability to bond with others
- 28. an element that readily forms cations and has metallic bounds
- 29. The organized array of all the chemical elements in order of increasing atomic number
