How many protons and neutrons are in the nucleus of a helium-4 atom if it has twice as many protons as a hydrogen atom?
A hydrogen atom has 1 proton in its nucleus. Since the helium-4 atom has twice as many protons as hydrogen, it has 2 protons. Helium-4 also has 2 neutrons, hence the name "4" representing the total number of protons and neutrons.
Can the atom of hydrogen does not have a proton in its necleus?
no. elements are categorized by the number of protons. also if there are no protons. then it is no longer an atom
What kind of atom has1 protons in its nucleus?
A stable atom of hydrogen (H)
Could the number of protons in the nucleus of an atom be unique for each element?
Yes, the number of protons defines what element it is. 1 proton = Hydrogen, 2 protons = Helium and so on
How is helium atom different from a hydrogen atom?
Helium has a nuclear charge of +2 and 2 electrons in a 1s orbital. Hydrogen has a nuclear charge of +1 and just one electron in a 1s orbital. The extra charge on the nuclees means that the electrons in He are more tightly bound than in hydrogen thuis reflected in the ionization energy of 2372 kJ/mol for He and about 1312 kJ/mol for hydrogen. For helium t the "outer shell" is full, a "stable " configuration.

How is the nucleus of the hydrogen atom different from the nucleus helium atom?
The nucleus of hydrogen has 1 proton, whereas that of helium has 2 protons.

What kind of atom has1 protons in its nucleus?

Where are the protons in a hydrogen atom?
in the nucleus
How many protons are there per atom?
The number of protons varies for different elements. For example, Hydrogen has only one proton in each atom. That's what makes hydrogen hydrogen. If it had two protons, it would be helium. If there were no protons, then it wouldn't be anything.
Protons in water molecule?
Water isn't an atom, its a molecule. One molecule of water is two hydrogen atoms (1 proton each) and one oxygen atom (8 protons each). Thus the total protons is 1+1+8 = 10 protons in one molecule of water.
How many number of protons in helium?
H2O has 10 protons. Hydrogen has 1 proton, so 2 hydrogen have 2 protons. Oxygen has 8 protons.
What atom do you build with 2 protons 2 neutrons and 2 electrons?
Helium-4 has 2 protons and 2 neutrons, and is formed both by the fusion of hydrogen in stars and in the decay of heavy radioactive elements. The neutral atom has 2 electrons.
Because a hydrogen atom does not contain a neutron hydrogen ions can be thought of as?
protons
Number of protons in a hydrogen?
The "NUMBER" (#) of Protons in an Atom of Hydrogen is one (1). The number of protons is what makes a specific element that element. Hydrogen always has one proton no matter what. If someone says that a hydrogen atom has two protons(they are incorrect), it is no longer hydrogen; it is the element Helium.
