Atoms and Periodic T
Question | Answer |
---|---|
How does an atom relate to an element, molecule, and compound? | Elements are more than one of the same atom. Molecules are a cluster of different atoms bonded together. Compounds are made of two or more molecules. |
Why are atoms neutral? | Atoms are neutral because the number of protons is equal to the number of electrons. |
What are some of the trends you find in the columns of the periodic table? | Trends include: the number of valence electrons are the same, they gain one more shell each time you move down, and the properties are the same. |
Given the information that sulfur is in the oxygen family, it has 6 valence electrons, oxygen has 8 electrons, and it is the second element down (columns), how many electrons does sulfur have? | Sulfur has 16 electrons. |
Why do compounds form and/or what does every atom want to become? | Atoms want to have full valence shells or look like the noble gases. |
What is the maximum amount of electrons allowed in the first three shells? | The maximum number in the first shell is two, the second shell is eight, and the third shell is eight. |
What three things can elements be classified as? | The three things are metals, non metals, and metalloids. |
Is an atom the smallest particle ever? | No, it is not. |
How many electrons are found in the outer shell of an element of the carbon family? | 4 electrons |
