The correct answer is:
a positron is emitted when proton converts to a neutron.

The reaction can be described as following:
₁¹p (proton) → ₀¹n (neutron) + ₁°e (positron or ₁⁰β)
Positron is an antiparticle of a β particle (₋₁°β), which means it has an oposite charge to it, but same mass.

A homogenous mixture has uniformly dispersed components while a heterogeneous mixture does not.

<h3>Homogenous vs heterogeneous mixtures</h3>

First of all, both homogenous and heterogenous mixtures consist of 2 or more non-reacting chemical components.

In homogenous mixtures, the chemical components are uniformly dispersed throughout the entire mixture.

In heterogeneous mixtures, the reverse is the case. The components are not uniformly dispersed. They are skewed to a particular side.
