periodic table with valence electrons and charges

Explain why the halogens generally have a negative charge. What is the general trend for increasing metallic character? 15. What is the general trend from left to right across a period for electronegativity? How can you explain this trend? Which element has the highest electronegativity? 14. A modified form of Coulomb's Law is written below, where e is the charge of an electron, Z e f f is the effective nuclear charge experienced by that electron, and r is the radius (distance of the electron from the nucleus). In your own words, define electronegativity. What are the eight elements touching the stairstep line on the periodic table classified as Metalloids.

Describe the properties attributed to most nonmetals. Describe the properties attributed to most metals.

Block Elements are organised into blocks by the orbital type in which the outer electrons are found. The atomic number of each element increases by one, reading from left to right. Earlier, we located the valence electrons for elements Z < 20 by drawing modified Bohr structures. Period A horizontal row in the periodic table. Label your periodic table with predicted charges from Bohr model. Which seven elements from the periodic table are metalloids? What are the properties of a metalloid? What group numbers contain metalloids? 11. Members of a group typically have similar properties and electron configurations in their outer shell. Moving across a period in the periodic table, each successive element adds one proton to its nucleus, increasing its positive charge by 1. Which group (name and number) from the periodic table contains atoms with a stable outer electron configuration? Why are these elements so stable? 10. Review Question 28.Use the concepts of effective nuclear charge, shielding, and n value of the valence orbital to explain the trend in atomic radius as you move across a period in the periodic table. In what column of the periodic table would you expect to find atoms with 7 valence electrons? List one of these atoms. This periodic table with charges is a useful way to keep track of the most common oxidation numbers for each element.
