Pleaseeeeeeeeeeeeee please helpYou have learned that the atomic number of a chemical is the number of protons found in the nucleus. Atomic numbers can be used to find the number of neutrons and electrons in an atom. In this project, you will practice atomic mass and atomic mass number calculation as well as fill out a chart using the periodic table. Don’t forget to read through the rubric below, so you will know what you will be graded on. When you are ready, upload it replacing the “Lastname” in the saved document name with your last name. Part I: The atomic number of the sodium atom is 11. The atomic mass number can be estimated by rounding the atomic mass to 23. From this information, you can find the number of neutrons: 11 protons plus how many neutrons equals a mass number of 23? The number of neutrons would have to be the difference between 23 and 11, which is 12. This fact can be restated this way: 11 protons plus 12 neutrons equals a mass number of 23. For every proton in the nucleus, an electron revolves around the nucleus. Since 11 protons are in sodium, 11 electrons must be in sodium. Using this information and the Periodic Table from lesson titled Periodic Table fill in the chart below. Element Atomic Number Atomic Mass How many neutrons? How many electrons? How many protons?

The answer is option A

How many significant figures does 546.000 have

Answers

This has only only three sig figs because it is 546.000 the zeros are just place holders so thus meaning they are not significant. It is just another way to write 546 because in that number there is also 3 sig figs. They are just trying to throw you off. Just watch out because if the example is 540 then it is just two significant digits, and it were to be 540. then it be three cause that "." makes the zero significant.

The type of bond between atoms of potassium and chloride in a crystal of potassium chloride a. hydrogen bond
b. ionic bond
c. polar covalent bond
d. pure covalent bond
e. metallic bond

Answers

It's an ionic bond because potassium is a metal and chlorine is a non-metal so the potassium donates an electron to the chlorine and so the potassium becomes a positive ion and the chlorine becomes a negative chloride ion. Opposite ion charges attract so an ionic lattice is formed.

6 A bulb thermometer gives an indoor temperature reading of 21 degrees Celsius. A digital thermometer in the same room gives a reading of 20.7 degrees Celsius. Which devise is more precise? Explain.

I think the digital thermometer is more precise because it can measure decimals, then the reading is closer to the right temperature. The other thermometer can't read decimals.

What is the pH of a solution that contains a pOH of 7.9?

Answers

pH and pOH are opposites, so pH can be determined by subtracting pOH from 14
pH = 14 - 7.9 = 6.1
