Hint 2. Identify the periodic trends of metallic character on the periodic table Complete each statement about the general trends in metallic character on the periodic table. Drag each item to the appropriate bin. Hint 1. The definitions of groups and periods In the periodic table, groups occur in vertical columns, while periods occur in horizontal rows. ANSWER:
ANSWER: Correct Electron Configurations and the Periodic Table In the periodic table elements are organized by atomic number, the number of protons in an atom. The vertical columns in a periodic table are called groups , while the horizontal rows are called periods . Atomic number increases from left to right across a period and from top to bottom down a group. A neutral atom has the same number of electrons as protons. You can use the atomic number to find the number of electrons in the neutral atom, and start building an electron configuration. The outer electron configuration of an element includes everything except the noble-gas core. For example, the element C [He]2 2 2 2 2 2 2 2
has an electron configuration of and an outer electron configuration of . The inner electron configuration of an element includes only the noble-gas core. The element has the inner electron configuration of . Part A Classify each statement as true or false. Drag the appropriate items to their respective bins. Hint 1. Define terms related to electron configurations Match the terms on the left with the sentences on the right. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. [He]2 2 s 2 p 2 2 2 s 2 p 2 C [He] n
Hint 2. Identify trends on the periodic table Classify each statement as true or false. Drag the appropriate items to their respective bins.
Correct ANSWER: All attempts used; correct answer displayed Part B Arrange the elements in decreasing order of the number of valence electrons. Rank from most to least number of valence electrons. To rank items as equivalent, overlap them.
