Interpretation:
The name and describes the two change states of mater should be explain.
Concept Introduction:
Matter: It can exist one of three main states, like solid, liquid and gas, solid matter is composed to tightly packed partials, a solid will becomes it shape, and the partial are not free to move around. Than liquid matter is made of more loosely packed particles, gas molecule completely loosed particles.
Phase changes: The phase changes include vaporization, condensation, melting, freezing, sublimation and deposition. For example vaporization occurs when moved particles of a liquid reach a high enough energy to leave the surface of the liquid and change into the gas state. Then another example the evaporation is a puddle of water draying out.

- An isotope of sodium (Na) has a mass number of 22. How many neutrons does it have? a. 11 b. 12 c. 22 d. 44arrow_forwardPolonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. For example, they can be stopped by a single sheet of paper or a few inches of air. That is one reason that authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po become after it emits an alpha particle?arrow_forwardMagnesium has an atomic number of 12. Which of the following statements is true of a neutral magnesium atom? a. It has 12 protons, 12 electrons, and 12 neutrons. b. It has 12 protons, 12 electrons, and six neutrons. c. It has six protons, six electrons, and no neutrons. d. It has six protons, six electrons, and six neutrons.arrow_forward
- Which element has only one proton?arrow_forwardPolonium is a rare element with 33 radioisotopes. The most common one, 210Po, has 82 protons and 128 neutrons. When 210Po decays, it emits an alpha particle, which is a helium nucleus (2 protons and 2 neutrons). 210Po decay is tricky to detect because alpha particles do not carry very much energy compared to other forms of radiation. They can be stopped by, for example, a sheet of paper or a few inches of air. This property is one reason why authorities failed to discover toxic amounts of 210Po in the body of former KGB agent Alexander Litvinenko until after he died suddenly and mysteriously in 2006. What element does an atom of 210Po decay into after it emits an alpha particle?arrow_forwardChlorine is an element with the symbol Cl. Draw and label atomic structure of chlorine indicating the number and locations of protons, neutrons and electrons in one atom of chlorine.arrow_forward
- The atomic number of an atom is determined by the number of in the atom. (a) protons (b) neutrons (c) electrons (d) electrons plus neutrons plus protonsarrow_forwardWhat is the smallest unit of an element that retains the properties of that element?arrow_forwardElements have varying numbers of protons, neutrons, and electrons.True or false?arrow_forward
- Where within an atom are the three types of subatomic particles located?arrow_forwardWhich of the following has the highest iodine content? Which of the following has the lowest melting point? Which of the following requires the fewest moles of hydrogen for complete hydrogenation? Which of these is likely to be solid at room temperature?arrow_forwardWhich elements in each pair is more metallic? Silicon or aluminumarrow_forward
