Answer:
Alpha particles are energetic (fast) helium nuclei, beta particles are smaller and have half the charge, being energetic electrons (or positrons) only the gamma particles are photons, i.e., they are not massive particles at all, they are a form of electromagnetic radiation, a form more energetic than X-rays
Objects with more mass have more gravity. Gravity also gets weaker with distance. So, the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass.
In chemistry:
The <u>molar mass</u> is the mass of a chemical element or compound divided by the amount of substance in the element.
The ability for gas to mix with other or multiple substances is diffusion
<h3><u>Answer and explanation</u>;</h3>
- To balance the charges of ions the number of electrons lost is equal to the number of electrons gained. The overall net charge must be zero.
- The number of ions needed to accomplish this is represented by the subscripts.
- For any given ionic compound, the product of the charge on the ion (or multiatomic ionic group) times the subscript of the ion will give a total charge of zero when all ions are considered.
For examples: NaCl Na = +1 Cl = -1 total is zero
