Ionic bonds are formed between metal and nonmetal elements. potassium has only one valence electron and it is stripped away in the process of forming an ionic bond. nonmetals, such as chlorine, tend to gain valence electrons in the formation of ionic bonds. determine which element(s) are likely to have their electrons stripped away in the formation of ionic bonds. i) aluminum ii) sulfur iii) oxygen iv) silver v) neon a) ii and v b) i and iv c) i, ii, and iii d) iii, iv, and v

Acandle’s wick is the fabric string that holds the flame, and it burns down at a constant slow pace when the candle is lit. the wick is usually surrounded by wax. which is the most important property of covalent compounds that makes them useful for making candle wax? a low boiling point a low melting point a high boiling point a high melting point

Air pressure is measured in pascals. for a professional american football game, the ball should be inflated to about 90,000 pascals. scientists studied the effects of air temperature on the pressure inside american footballs by taking these steps: 1. prepare 100 footballs. 2. measure each football's air pressure. 3. divide footballs into 10 groups. 4. place the groups in different lockers cooled to different air temperatures. 5. after 12 hours, remove the footballs from lockers. 6. measure each football's pressure again. 7. compare the new pressures to the starting pressures. what two terms best describe the variable "air pressure inside the football" in this experiment? independent, qualitative independent, quantitative dependent, qualitative dependent, quantitative
