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?
Two and two
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.
How many electrons in an atom with 49 protons?
A neutral atom with 49 protons has 49 electrons.
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 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.
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?
Two and two
How many protons and electron in a francium atom?
Francium has 87 protons and 87 electrons.
How many valence electrons does HBr have?
Hydrogen has 1 valence electron. Bromine has 7 valence electrons. When hydrogen and bromine react, the bromine atom 'steals' the hydrogen atom's only electron. The hydrogen atom then has no electrons and the bromine atom has 8 valence electrons. The two atoms are now ions because their number of protons does not equal their number of electrons. The bromine atom is now a bromide anion and the hydrogen atom is now a hydrogen cation (a proton). The two ions remain together, ionicly bonded and together are called hydrogen bromide.
How many protons are in an atom which has 55 neautrons and 43 electons?
If this atom has 43 electron it must have 43 protons to be a neutral atom of no charge.
How many protons and neutrons does a hydrogen Atom contain?
One hydrogen atom contains one proton and one electron.
How many electrons are in hydrogen atom?
1 electron
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.
How many atoms are in the last shell of the hydrogen atom?
The hydrogen atom (1H) has only 1 proton and 1 electron (you probably think at this electron).
