Element with 207 as it atomic mass number?
The element with atomic mass number 207 is lead (Pb). Lead is a heavy metal that is commonly used in batteries, construction materials, and ammunition.
What is the relative atomic mass of lead?
The element lead consists of four naturally occurring isotopes with atomic masses 203.97302, 205.97444, 206.97587, and 207.97663 . The relative abundances of these four isotopes are 1.4, 24.1, 22.1, and 52.4%, respectively.
How many electrons are in lead outer shell?
82. Lead is an element with symbol Pb and atomic number 82. The atomic number relates to the amount of electrons of the element
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.

How many neutrons are in the average atom having an atomic mass of 207.2 grams per mole?
Look on the periodic table for the element with the closest atomic mass to that number. It's lead (Pb, #82.) Now, for the neutron count, you round that atomic mass to the nearest whole number, which is 207, then subtract the atomic number of 82 from it. 207-82=125. So 125 neutrons.
What is the atomic mass for magnesiam?
Magnesium is a meta element. Atomic mass of it is 24.
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
What has 86 electrons125 neutrons and 82 protons?
The element with 86 electrons, 125 neutrons, and 82 protons is the element Lead (Pb). The number of protons (atomic number) determines the element, and in this case, it is 82 for lead. The sum of protons and neutrons gives the atomic mass, which is 207 in this case, making it the isotope with mass number 207.
