Which type of particle has a negative charge? beto alpha gamma x-rays

## Step 1<br />The problem asks us to identify which type of particle among the given options has a negative charge. The options are beta, alpha, gamma, and x-rays.<br /><br />## Step 2<br />Beta particles are high-energy, high-speed electrons or positrons that are emitted by certain types of radioactive nuclei. They can be either negatively or positively charged, depending on whether they are electrons or positrons.<br /><br />## Step 3<br />Alpha particles are positively charged particles consisting of two protons and two neutrons. They are essentially helium-4 nuclei.<br /><br />## Step 4<br />Gamma rays are not particles but rather a type of electromagnetic radiation. They are neutral and do not carry any charge.<br /><br />## Step 5<br />X-rays are also a type of electromagnetic radiation and are neutral, similar to gamma rays.<br /><br />## Step 6<br />Among these options, beta particles are the only ones that can have a negative charge, specifically when they are electrons.
