Why do all lead atoms have 82 protons and 82 electrons?

Answer 1

Atomic Number: It is an experimentally determined number characteristic of a chemical element that represents the number of protons in the nucleus which in a neutral atom equals the number of electrons outside the nucleus. Therefore, a neutral atom of Pb (lead) would have 82 protons and 82 electrons.

Answer 2

An atom of lead has 82 protons in its nucleus.

Note, the atomic number of lead is 82 and this number always equals the number of protons in the atomic nucleus (and the number of electrons the neutral atom has).

Answer 3

All lead atoms have 82 protons and 82 electrons because the number of protons determines the element's identity. In a neutral atom, the number of protons equals the number of electrons to balance the positive and negative charges, maintaining overall neutrality. Therefore, lead atoms with 82 protons will also have 82 electrons.

Answer 4

The atomic # of Lead is 82... Thus Lead has 82 protons.

Answer 5

82 is the Atomic Number for lead and lead has 82 electrons, 82 protons and between 95 and 135 neutrons, depending on which isotope.

Answer 6

because the atomic number of lead is known to be 82 and as the equation states

atomic number=number of protons= number of electron

Answer 8

43

Answer 9

82
