3 0

I think a awsner could since heat makes molecules move faster causing them to be unstable thus increasing the rate for reaction

Describe the relationship between the atomic number, mass number, number of protons, number of neutrons.

Charra [1.4K]

Explanation:

Atomic number (Z) = Number of the protons

It means that if the atomic number of C is 6, it implies that the number of protons in carbon is 6 too.

Mass number (M) = Number of the protons + Number of the neutrons

It means that if the atomic mass of C is 12, it implies that the number of protons and the neutrons in carbon is 12.

When polonium-210 emits an alpha particle, the child isotope has an atomic mass of

Sergeeva-Olga [200]

Answer: The child isotope has an atomic mass of 206.

Explanation:

Alpha decay : When a larger nuclei decays into smaller nuclei by releasing alpha particle. In this process, the mass number and atomic number is reduced by 4 and 2 units respectively.

General representation of an element is given as: $_Z^A\textrm{X}$

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

General representation of alpha decay :

$_Z^A\textrm{X}\rightarrow _{Z-2}^{A-4}Y+_2^4\alpha$

$_{84}^{210}\textrm{Po}\rightarrow_{82}^{206}\textrm{Pb}+_2^4\textrm{He}$
