It's the number of protons.
The table of elements organizes the elements by their number of protons/the atomic number as the number of protons of an element is fixed, unlike the number of electrons and neutrons.

The atomic number of an atom is determined by the number of protons present in the atom that is the atomic number and number of protons are same for an atom. It is unique for every atom.

Atomic mass: It is nearly equals to the sum of mass of subatomic particles present in the atom that is sum of proton and neutron.

Number of neutrons: in an atom, the number of neutrons are always equal to the number of protons. If the number of neutrons are different for a number of proton then it is said be an isotope of that atom.

Protons plus neutrons: Sum of number of protons and number of neutrons is said to be the mass number of that atom.

Hence, the atomic number is the number of protons.

Which polymer structure should be used if a strong and heat - resistant adhesive is required?
alexira [117]

Cross-linked polymers are strong and heat - resistant hence they can be used for this purpose.

A polymer is obtained by the combination of small molecules called monomers. A polymer consists of a regular repeating unit of small molecules called monomers.

A cross-linked polymer is a polymer in which covalent bonds are used to join polymer chains together. Cross-linked polymers are strong and heat - resistant hence they can be used for this purpose.

When a cell is in a solution where the concentration of solute is the same in the cell as in the solution, the solution is calle
Elodia [21]
The answer to this question would be: isotonic

An isotonic solution has a same tonicity/concentration to the cell. This kind of solution will not cause osmosis to occur so it wouldn't shrink or swell the cells. This is why an isotonic solution is safer for the cells. The normal saline solution is isotonic to human cells and used frequently in medicine to replace body fluid.

Which statement best describes the collisions of gas particles according to the kinetic-molecular theory?
erastovalidia [21]
<span>The statement best describes the collisions of gas particles according to the kinetic-molecular theory is that the collisions of gas particles in an ideal gas are completely elastic. An expansion in the quantity of gas particles in the holder expands the recurrence of impacts with the dividers and in this manner the weight of the gas. The last propose of the motor sub-atomic hypothesis expresses that the normal active vitality of a gas molecule depends just on the temperature of the gas.</span>
