The most common form of Hydrogen, forming more than 99.9% of all hydrogen atoms in the universe, (sometimes known as Hydrogen-1) has one proton in the nucleus and one electron ( with no neutrons ).
There are, however, other forms (isotopes) of hydrogen that can be stable, such as Hydrogen-2 ( also known as deuterium ), which has one neutron and one proton in the nucleus as well as one electron.

How many protons and neutrons are in the element?
Neon has 10 protons and 9 neutrons.
How many protons does hydrogen-1 have?
HydrogenAll atoms, ions, and isotopes of the same element have the same number of protons. The number of protons defines the element. Hydrogen atoms all have one proton. So it does not matter if you provide the mass number (hydrogen-1) because the number of protons does not depend on it. It does, however, let us know the number of neutrons. The mass number is the sum of the number of protons and neutrons. Because we know that hydrogen has one proton, and the mass number is one, there must be no neutrons.
How many protons and neutrons and electrons does the element gold?
Neutrons - 118 Protons/electrons - 79
How many protons neutrons and electrons does an element have?
An element must always have the same number of protons as it's atomic number. The number of electrons may vary, making an atom into an ion, and the number of neutrons can also vary which is why we have different isotopes of the same element.
How many protons and neutrons are there in the element scandium?
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
How many protons electron and neutrons does oxygen?
Oxygen is a p block element. It has 8 protons and neutrons.
How many neutrons the element H has?
Hydrogen has 0 neutrons
How many protons and neutrons does a nucleus of an atom contain?
Each element has a different number of protons and neutrons. So it changes for each element.
How many core atoms are in as atom?
An atom is made up of protons neutrons and electrons. Hydrogen has 1 proton and 1 electron. The numbers will vary from element to element.
Why must you know both how many protons and how many neutrons an element has in order to fully identify it?
The number of protons determine what element it is, the number of neutrons determine what isotope it is.
Why do different atoms of the same the same element have the same atomic number but different mass numbers?
The atomic number of an element tells you how many protons an atom has in it's nucleus, and each element is defined by the number of protons it has. For example hydrogen always has 1 proton. The Mass number tells you how many protons and neutrons there are in an atom. However it is possible for an element to have different numbers of neutrons in the nucleus. When this occurs you will get different masses for the same element but the same atomic number. Two (or more) elements are known as isotopes if the only difference between them is the number of neutrons. Probably the most common/well known example of an isotope is Hydrogen, Deuterium (Hydrogen with a neutron) and Tritium (Hydrogen with 2 neutrons)
How many protons and neutrons and electrons does the element gold have?
In a regular sample of the element of gold, meaning no change done to it, then there will be 79 protons and 118 neutrons
