What is the protons number of lead?

What is the protons number of lead?

Lead/Atomic number

How are protons neutrons and electrons organized?

The protons and neutrons are found in the nucleus at the centre of the atom. The nucleus is very much smaller than the atom as a whole. The electrons are arranged in shells around the nucleus.

What is the number of electrons of lead?

Lead/Electrons per shell

How are the number of electrons and protons related?

It illustrates some basic information like the number of protons and neutrons in the nucleus. It also shows that the number of electrons is the same as the number of protons. This model also shows that some electrons can be close to the nucleus and others are further away.

How is the number of electrons and neutrons calculated?

Protons are positively charged, electrons are negatively charged, and neutrons have no (neutral) charge. Thanks! How do I calculate the electron, proton and neutron? The atomic number is the proton. The number of electrons in an atom is always the same as the number of protons in the nucleus, unless it is an isotope.

How many protons and electrons are in a lithium atom?

For example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4). Isotopes are various forms of an element that have the same number of protons, but a different number of neutrons.

How are protons and neutrons alike and different?

Protons and neutrons both weigh about one atomic mass unit or amu. Isotopes of the same element will have the same atomic number but different mass numbers. Atomic number, chemical symbol, and mass number: Carbon has an atomic number of six, and two stable isotopes with mass numbers of twelve and thirteen, respectively.
