How many protons, neutrons, and electrons are there in a neutral atom of 113in (indium-113)?
Hope it helps !!!
Explanation: In a neutral atom the number of protons equal the number of electrons. Also, it is known that atomic number means number of protons. Atomic number of indium is 49 that means number of protons in indium is 49. Since it is a neutral atom so, number of electrons in an indium atom is also 49. Whereas mass number means sum of total number of protons and neutrons. Mass number = no. of protons + no. of neutrons 113 = 49 + no. of neutrons no. of neutrons = 113 – 49 = 64 Hence, in a neutral indium atom no. of protons = no. of electrons = 49 and no. of neutrons is 64.
Number of Protons = 19 Number of Neutrons = 25 Number of Electrons = 19 Explanation: Number of Protons: The number of protons present in any atom are equal to the atomic number of that particular atom. Hence, as the atomic number of Potassium is 19 therefore, it contains 19 protons. Number Neutrons: The number of neutrons present in atom are calculated as, # of Neutrons = Atomic Mass – # of protons As given, Atomic Mass = 43 # of Protons = 19 So, # of Neutrons = 43 – 19 # of Neutrons = 24 Number of Electrons: As we know for a neutral atom the number of electrons are exactly equal to the number of protons present in its nucleus. So, for 19 protons in neutral Potassium atom there must be 19 electrons.
26 protons, 29 neutrons, and i believe 26 electrons

Answer 6
Protons = Electrons = 43 Neutrons = 54 Explanation: Technetium is transition metal and belongs to the 5d-series in the periodic table. Tc- 97 has an atomic number Z = 43 and Atomic mass A = 97 For a neutral atom: Atomic number = number of protons = number of electrons Atomic mass = number of protons + neutrons For Tc-97: Z = 43, therefore Protons = 43 Electrons = 43 A = 97 i.e. 97 = 43 – neutrons # neutrons = 97 – 43 = 54
Answer 7
There are 53 protons, 53 electrons and 78 neutrons in a neutral atom of iodine-131. Explanation: Iodine-131 is a radioactive isotope of iodine-127. An isotope is an atom that has the same atomic number but different weight atomic of its original atom. Iodine-127 has: – Atomic number = 53 – Atomic weight = 127 – Protons = 53 – Electrons = 53 – Neutrons = Atomic weight – Atomic number = 127 – 53 = 74 Iodine-131 has: – Atomic number = 53 – Atomic weight = 131 – Protons = 53 – Electrons = 53 – Neutrons = Atomic weight – Atomic number = 131 – 53 = 78
