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:
Step 1: Recall element - proton relationship
The atomic number of an element is equal to the number of protons in its nucleus. This number uniquely identifies the element.
Step 2: Identify element for part a
Since there are 26 protons, looking at the periodic table, the element is Iron (Fe).
Step 3: Identify element for part b
With 53 protons, the element is Iodine (I).
Step 4: Identify element for part c
For a neutral atom with 2 electrons, the number of protons is also 2. The element is Helium (He).
Step 5: Identify element for part d
Having 20 protons, the element is Calcium (Ca).
Step 6: Identify element for part e
With 82 protons, the element is Lead (Pb).
Step 7: Identify element for part f
An atom with 0 neutrons and 1 proton is Hydrogen (H).
Answer:
a. Iron (Fe) b. Iodine (I) c. Helium (He) d. Calcium (Ca) e. Lead (Pb) f. Hydrogen (H)
