Phosphorus - P - Protons = 15, Electrons = 15, Neutrons = 16 - Non-Metal
Lithium - Li - Protons = 3, Electrons = 3, Neutrons = 4 - Metal
Nitrogen - N - Protons = 7, Electrons = 7, Neutrons = 7 - Non-Metal
Copper - Cu - Protons = 29, Electrons = 29, Neutrons = 34 - Metal
Neon - Ne - Protons = 10, Electrons = 10, Neutrons = 10 - Non-Metal
sorry i don’t know about the other questions but i thought i could help with the table!
Additional Info:
number of protons = atomic number
number of electrons = atomic number
number of neutrons = mass number - atomic number
Answer:
When a front passes over an area, it means a change in the weather. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.

Answer:
Mass of water = 6251. 706g or 6.25Kg
Explanation:
Relative humidity = (actual vapor pressure/saturation vapor pressure) * 100%
Actual vapor pressure, Pw = relative humidity * saturation vapor pressure
Pw = 60% * (35.6 *0.001)atm = 0.0216atm
Note: 1mbar = 0.001atm
Using the ideal gas equation: PV=nRT; where P = Pw= 0.02136atm, V= (400
* 1000)dm^3, R= 0.082 atmdm^3/kmol, T= (27+273)K, n = number of moles
Note: 1m^3 = 1000dm^3,R is the molar gas constant.
Making n subject of the formula, n = PV/RT
n= (0.02136 * 400000)/(0.082 * 300) = 347.317 moles
Mass (g) = number of moles (n) * molar mass
molar mass of water=18g
Mass of water = 347.317 * 18 = 6251. 706g or 6.25Kg

Explanation:
There is an evident reason why some of the solutions Carson's has listed and observed, does conduct electricity and some that do.
A flow of electrical charge is called an electric current. Ions are atoms, or sets of atoms, that contain an electrical charge. There are two types of ions, cation or a positively charged ion containing a deficiency of electrons, and anion or a negatively charged ion which contains a surplus of electrons. When a solution conducts electricity the charge is carried within by ions that move through the solution. The larger the number of ions in the solution, the better the conductivity of the solution is. Pure water does not conduct very well because it contains very few ions, but when table salt (NaCl) is dissolved in the water, this solution does conduct well because the solution contains a more abundance of ions. The majority of the ions come from the table salt, chemically names sodium chloride. Because Sodium contains its sodium ions, and these are positive charge and chloride ions which is a negative charge, it is called an ionic substance. Not every substance is made up of ions, one such example is sugar (C12H22O11). Sugar is made up of uncharged particles also called molecules. Although sugar is a substance its molecules do not hold a charge, thus when sugar is dissolved in water, the solution does not conduct electricity, due to the lack of ions in the solution.
Therefore, depending on the ions that make up the compound, the substance would or would not conduct electricity.
