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)
