10. name the element which has the following numbers of particles:\na. 26 electrons, 29 neutrons, 26 protons\nb. 53 protons, 74 neutrons\nc. 2 electrons (neutral atoms)\nd. 20 protons\ne. 86 electrons, 125 neutrons, 82 protons (charged atom)\nf. 0 neutrons
Answer
Explanation:
Step1: Recall the rule for element identification
The number of protons in an atom determines the element.
Step2: Identify element for part a
Since there are 26 protons, the element is iron (Fe).
Step3: Identify element for part b
With 53 protons, the element is iodine (I).
Step4: Identify element for part c
For a neutral atom with 2 electrons, there are also 2 protons, so the element is helium (He).
Step5: Identify element for part d
Having 20 protons, the element is calcium (Ca).
Step6: Identify element for part e
The number of protons is 82, so the element is lead (Pb).
Step7: Identify element for part f
The only element with 0 neutrons is hydrogen (H).
Answer:
a. Iron (Fe) b. Iodine (I) c. Helium (He) d. Calcium (Ca) e. Lead (Pb) f. Hydrogen (H)
