Which of the following denotes the massive positively charged, nuclear particles? Isotopes Electrons Neutrons Protons IDONT KNOWYET

## Step 1<br />The question asks us to identify the massive, positively charged nuclear particles among the given options. <br /><br />## Step 2<br />Let's analyze each option:<br />- Isotopes: These are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. They are not particles but rather types of atoms.<br />- Electrons: These are subatomic particles that carry a negative charge. They are not positively charged.<br />- Neutrons: These are subatomic particles found in the nucleus of an atom. They carry no charge, hence they are neutral.<br />- Protons: These are subatomic particles found in the nucleus of an atom. They carry a positive charge.<br /><br />## Step 3<br />Based on the above analysis, the only option that denotes massive, positively charged nuclear particles is "Protons".
