How many atoms are in lead?
One mole of lead (Pb) contains 6.02 × 1023 atoms and its mass is 207.2 g.
How do you find number of electrons?
The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.
What are protons and neutrons?
Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom's nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral).

What is lead made of?
Lead is a soft, malleable, ductile and dense metallic element. It is extracted chiefly from the mineral galena and found in ore that also contains zinc, silver and copper. The chemical properties of lead allow this element to be used in power storage and delivery applications.
What is the atomic mass of lead?
207.2 uLead / Atomic mass
How do you find neutrons?
For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
How many electrons are in an element?
Finding the Number of Electrons The number of electrons in an atom is equal to the atomic number of an element, for neutrally charged species. This means the number of electrons and the number of protons in an element are equal. Therefore, the number of electrons in oxygen is 8.
How many protons and electrons are in each atom?
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
What ion is lead?

126 neutrons Rafal Broda (IFJ PAN), the first author of a publication distinguished by the journal Physical Review C, and explains: "The nucleus of lead-208 consists of 82 protons and 126 neutrons and, with a very good approximation, can be considered spherical.
Why are pencils called lead?
Because chemistry was a young science at the time, people thought graphite was a form of lead; hence the name given to pencils. The next step in the evolution of the pencil came in the late 1500s, when graphite rods were placed inside wood sleeves that were glued together. This made pencils easier to use.
Why is lead called lead?
When metallurgists first encountered this substance, they thought it was some sort of black lead, rather than a form of carbon. Thus, they called it “plumbago”, which is derived from “plumbum”, which is Latin for “lead”.
