Question

1. name the element which has the following numbers of particles. be specific. (include charges and mass numbers where possible.) 26 electrons, 29 neutrons, 26 protons 53 protons, 74 neutrons 0 neutrons 8. if you know only the following information can you always determine what the element is? (yes/no). information yes or no number of protons number of neutrons number of electrons in a neutral atom

Explanation:

Step1: Identify element by protons

The number of protons determines the element. For 26 protons, it's iron (Fe), mass - number = 26 + 29 = 55. For 53 protons, it's iodine (I), mass - number = 53+74 = 127. For 0 neutrons and 1 proton, it's hydrogen (H).

Step2: Determine element - identification info

Number of protons always determines element. Number of neutrons doesn't as isotopes exist. In a neutral atom, number of electrons = number of protons, so it can determine element.

Answer:

1. Fe (iron), mass - number 55
2. I (iodine), mass - number 127
3. H (hydrogen)
4. Yes
5. No
6. Yes
