Radium-226 is unstable. what is the process that allows the nucleus of radium-226 to become more stable? question 14 options: a. ionic bonding b. radioactive decay c. hydrogen bonding d. covalent bonding e. nuclear fusion

The correct answer is Option B.

Explanation:

We are given a radioisotope which is unstable in nature. For this isotope to become stable, it has to undergo radioactive decay. There are various processes by which a radioisotope may decay:

1. Alpha decay: In this decay process, a heavier nuclei decays into lighter nuclei. The particle released is alpha particle.

2) Gamma decay: In this decay process, an unstable nuclei gives excess energy by a process of spontaneous electromagnetic process. This decay process releases .

3) Beta-plus decay: In this decay process, a neutron gats converted into a proton and an electron. The particle released is

4) Beta-minus decay: In this decay process, a proton gets converted into a neutron and an electron neutrino which is known as a positron particle. This is also known as -decay.

Radium-226 nuclei undergoes alpha decay to form Radon-222 nuclei by releasing alpha-particle.

Hence, the answer is Option B.

the correct answer for this question is radio active decay or option b ! press brainliest...

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
