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.
How many electrons protons and neutrons are there in each Hydrogen and oxygen atom?
A hydrogen atom typically has one proton and one electron, with no neutrons in its most common isotope. An oxygen atom has eight protons, eight electrons, and usually eight neutrons, though there are isotopes of oxygen that may have different numbers of neutrons.
How many protons and neutrons does a hydrogen Atom contain?
One hydrogen atom contains one proton and one electron.
How many protons and electrons does hydrogen?
A hydrogen atom has 1 proton and 1 electron regardless of the isotope.Standard hydrogen(protium) has zero neutrons.The deuterium isotope has 1 neutron and the tritium (very radioactive) has 2 neutrons.
What is the smallest atom?
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
How many protons neutrons and electrons has?
Hydrogen is a nonmetal gas. An atom has 1 proton and one electron.
How many protons neutrons electrons and valence electrons are there in each atom in hno3?
In each atom of HNO3: There is 1 proton in the hydrogen atom, 7 protons in the nitrogen atom, and 16 protons in the oxygen atom. The number of neutrons can vary since it depends on the isotope of each element. There are 1 electron in the hydrogen atom, 7 electrons in the nitrogen atom, and 16 electrons in the oxygen atom. Each atom in HNO3 has 1 valence electron.
How many electrons that a hydrogen atom shares?
Hydrogen atoms have one valence electron which is also the only electron they have.
How many electron are in neautral hydrogen atom?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
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.
How many electrons and protons does an atom have?
Well it depends on the atom. Like for instance Hydrogen has 1 electron and 1 proton and Nitrogen has 7 protons and 7 electrons. If the atom is charged, then the number of protons and electrons are not equal. For example, hydrogen ion with +1 charge has 1 proton and 0 electrons. If the number of electrons is the same as the number of protons, then it is said to be neutral.
H2 Has how many protons neutrons and electrons?
hydrogen has 1 proton and 1 electron, thus h2 has two of both.
How many protons neutrons and electrons are in hydrogen?
Hydrogen - 1 proton, 1 electron Deuterium - 1 proton, 1 neutron 1 electron Tritium - 1 proton, 2 neutrons, 1 electron
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.
How many valence electrons does a hydrogen atom have?
A hydrogen atom has 1 valence electron.
How many protons and electron in a francium atom?
Francium has 87 protons and 87 electrons.
How many electrons protons and neutrons are there in each Hydrogen and oxygen atom?
A hydrogen atom typically has one proton and one electron, with no neutrons in its most common isotope. An oxygen atom has eight protons, eight electrons, and usually eight neutrons, though there are isotopes of oxygen that may have different numbers of neutrons.
