Answer:
positively charged nucleons are 24
Explanation:
Given element:
₂₄⁵⁰ Cr
The superscript before the symbol of the atoms is mass number
The subscript before the symbol is the atomic number
Cr is the symbol of the atom
Now,
Atomic number is the number of protons in an atom.
The protons are the positively charged particles in an atom.
For this specie, the positively charged nucleons are 24
Explanation:
momentum increases with an increase in mass and velocity
Answer:
The final concentration of the Randyne in grams per milliliter = 0.011 g/mL
Explanation:
As we know
C1V1 = C2V2
C1 and C2 = concentration of solution 1 and 2 respectively
V1 and V2 = Volume of solution 1 and 2 respectively
Substituting the given values, we get -
mg/mL
The final concentration of the Randyne in grams per milliliter = 0.011 g/mL
<span>Dalton's atomic theory originally has 5 postulates. Among the choices, there are three that are included. These are:
*atoms of one element cannot change into atoms of another element.
</span><span>*each element is composed of tiny, indestructible particles called atoms.
</span><span>*atoms combine in simple, whole number ratios to form compounds
The others are incorrect. Atoms of one element cannot change to another element. Atoms of the same element do not have the same mass because they can occur as isotopes. Nuclear particles are not part of Dalton's theory, just the chemical reactions.</span>
