Correct options are highlighted when revealed.

1.Identify the incorrect statement regarding radioactive decay:

When a radioactive element emits an alpha particle, it becomes negatively charged.Emission of a beta particle from a radioactive substance results in a positive charge.A radioactive substance with a half-life of 20 years will be fully decayed after 40 years.The decay constant of a radioactive isotope does not depend on temperature, pressure, or concentration.

2.Identify the incorrect statement from the following options:

Atoms having identical mass numbers but differing atomic numbers are known as isobars.Atoms with the same number of protons but varying mass numbers are referred to as isoters.Among alpha, beta, and gamma radiation, gamma rays possess the highest penetrating ability.When an alpha particle is emitted, the resulting nucleus has a mass number reduced by four compared to the original.

3.Identify the incorrect statement from the following options:

The nucleus of a hydrogen atom consists solely of a proton.A beta (β) particle is essentially an electron.An electron's mass is approximately 1/1800th that of the lightest nucleus.A positron has a greater mass than a proton.

4.Identify the incorrect statement from the following:

The density ratio of the nucleus compared to the entire atom is 10¹².An alpha particle is essentially a helium ion with a +2 charge.The mass of a deuterium atom is approximately half that of a helium atom.Gamma rays consist of highly energetic electrons.

5.Which of the following statements is true?

A positron is the electron's antiparticle.During alpha decay, the neutron-to-proton ratio increases.Beta particles have greater ionizing ability than alpha particles.Alpha particles travel faster than gamma rays.

6.Which of the following statements is accurate?

Neutral atoms lose electrons to form negatively charged ions.The approximate size of the nucleus is 10^-12 cm, while the atomic radius is about 10^-8 cm.Neutral atoms gain electrons to create positively charged ions.In a stable nucleus, the ratio of protons to neutrons is 2 to 1.
