name the elementwhich has the following numbers of particles:

a.26 electrons,29 neutrons,26 protons
b.53 protons,74neutrons
c.2electrons(neutral atom)
d.20 protons
e.86electrons,125neutrons,82protons(charged atom)
f.0 neutrons

a. Look on the periodic table. 26 protons and 26 electrons tells you the element is #26.

b. 53 protons; element #53.
c. 2 electrons(neutral) so that means 2 protons, also. Element #2.
d. 20 protons. Element #20.
e. 0 neutrons. There is only 1 element with no neutrons. It has a mass of 1.

53 protons, 74 neutrons =Iodine.

2 electrons [ neutral atom] =Helium.
20 protons =calcium.
86 electrons, 125 neutrons, 82 protons [charged atom =lead
0 neutrons =Hydrogen
26 electrons, 29 neutrons, 26 protons =Iron

a. The element with 26 electrons, 29 neutrons, and 26 protons is Fe (Iron).

b. The element with 53 protons and 74 neutrons is I (Iodine).
c. For an atom with 2 electrons, it could be either H (Hydrogen) or He (Helium) since they both have 2 electrons in their neutral state.
d. The element with 20 protons is Ca (Calcium).
e. The element with 86 electrons, 125 neutrons, and 82 protons is Pb (Lead). However, you mentioned it as a charged atom, so it would be indicated as Pb2+ (Lead ion with a +2 charge).
f. An atom with 0 neutrons is H (Hydrogen). Please note that most hydrogen atoms have only 1 proton and 1 electron, but can have 0 neutrons in its most common isotope, known as protium.

To determine the element based on the given numbers of particles, we need to consider the atomic number and mass number.

a. The element with 26 electrons, 29 neutrons, and 26 protons corresponds to the atomic number of 26, which is iron (Fe).

b. For the element with 53 protons and 74 neutrons, we consider the atomic number of 53, which corresponds to iodine (I).

c. An atom with 2 electrons is neutral, so we need to find an element with an atomic number of 2. The element with atomic number 2 is helium (He).

d. When an atom has 20 protons, we consider the atomic number of 20, which corresponds to calcium (Ca).

e. For the atom with 86 electrons, 125 neutrons, and 82 protons, we need to consider both the atomic number and charge. The atomic number 82 corresponds to lead (Pb). Since there are 86 electrons, it is negatively charged, specifically Pb2-.

f. An atom with 0 neutrons indicates that it only contains protons and electrons, which means it is a hydrogen isotope known as hydrogen-1 or simply hydrogen (H).

Remember, the atomic number represents the number of protons, and the mass number represents the sum of protons and neutrons. By knowing this, we can determine the elements based on the given numbers of particles.
