What kind of bond is lithium fluoride?
What kind of bond is lithium fluoride? ionic bonds What happens when you mix lithium and fluoride? Lithium Fluoride One lithium (Li) atom can combine with one fluorine (F) atom. Together, they make the formula LiF. Fluorine has seven electrons of it’s own. Lithium gives up its one electron to make both atoms happy. What […]
What is the basic steps of scientific method?
What is the basic steps of scientific method? The basic steps of the scientific method are: 1) make an observation that describes a problem, 2) create a hypothesis, 3) test the hypothesis, and 4) draw conclusions and refine the hypothesis. What are the first three steps of scientific inquiry? Answer. Answer: The basic steps of […]
How do you know which element has the highest electron affinity?
How do you know which element has the highest electron affinity? Since this electron is farther away, it should be less attracted to the nucleus and release less energy when added. However, this trend applies only to Group-1 atoms. Electron affinity follows the trend of electronegativity: fluorine (F) has a higher electron affinity than oxygen […]
What did Wilson and Penzias discovery?
What did Wilson and Penzias discovery? However, when Arno Penzias and Robert Wilson studied cosmic radiation in 1964, they discovered that microwaves with a wavelength of about 7 centimeters were stronger than expected. This cosmic background radiation probably is a remnant of the Big Bang when the universe was created. How is CMB detected? The […]
What is done with the oxygen left as a product of photosynthesis?
What is done with the oxygen left as a product of photosynthesis? Photosynthesis uses energy from light to convert water and carbon dioxide molecules into glucose (sugar molecule) and oxygen (Figure 2). The oxygen is released, or “exhaled”, from leaves while the energy contained within glucose molecules is used throughout the plant for growth, flower […]
When an atom loses an electron The resulting ion will be a quizlet?
What happens immediately after a skydiver opens her parachute?
What happens immediately after a skydiver opens her parachute? What happens immediately after a skydiver opens his or her parachute? and why? The air resistance greatly increases and the skydivers speed decreases. The parachute opens up and doesnt allow the air to flow through it, which is air resistance. Fluid friction acting on an object […]
Which symbol is used to show that the switch is on?
Which symbol is used to show that the switch is on? IEC 60417-5010, the power on-off symbol (line within a circle), is used on buttons that switch a device between on and fully off states. What is the symbol of closed switch? Circuit Symbols 101 Switches Component Function of Component Push-to-Break Switch This type of […]
How do you identify cleavage?
How do you identify cleavage? Identifying Cleavage Planes: Since cleavage planes are always parallel to crystal faces, or possible crystal faces, they are identified with Miller indices, in the same way as are crystal faces. If the cleavage plane is parallel to the (111) face, then it is the 111 cleavage plane. What are the […]
