Answer:
The electron
Explanation:
The electron will be the lightest subatomic particle.
Answer:
The electron
Explanation:
Electron, lightest stable subatomic particle known. It carries a negative charge, which is considered the basic unit of electric charge. The rest mass of the electron is 9.10938356 × 10 −31 kg, which is only 1/1,836 the mass of a proton.

Explanation:
What is the most likely reason that nonmetals are electrical insulators?
Since valence shells are mostly empty in nonmetal atoms, the atoms attract and hold any electrons they can in order to fill their valence shells.
Since valence shells in nonmetal atoms are almost full, the atoms attract electrons and hold them tightly to fill their valence shells.
Since all nonmetals have valence shells that are full, they hold electrons tightly to avoid changing.
Since all nonmetals have valence shells that are completely empty, they do not attract or release any electrons.
Answer:
Since valence shells are mostly empty in nonmetal atoms, the atoms attract and hold any electrons they can in order to fill their valence shells.

Answer:
11.495 grams
Explanation:
A student finds a rock on the way to school. In the laboratory he determines that the volume of the rock by placing the rock in a graduated cylinder with 50 mL of water and watched the water rise to 72.7 mL. The student determined the mass is 39.943 g through the use of a triple beam balance. What is the density of the rock?
Answer:
1.76 g/mL
Explanation:
You need to find the volume. You can do this by subtracting the volume of the water and the rock by the volume of the water.
72.7 mL - 50 mL = 22.7 mL
Now that you have volume, divide the mass by the volume to find the density.
39.943 g/22.7 mL = 1.76 g/mL

describe a procedure to remove the water from the mixture that passes through the filter and collects in the beaker.
Answer:
The procedure is Filtration
Explanation:
Filtration is a process that is use to separate insoluble solid from liquid for example Salt and water.
This process uses filter paper which is placed inside a funnel and then placed inside a beaker.
The mixture of sand and water is poured into the the filter paper and water then drains out down to the funnel and the beaker.
The solid part remain at the filter paper and it is called the residue and the water is the filtrate.
