Which element has fewer protons neutrons?
Only two stable nuclides have fewer neutrons than protons: hydrogen-1 and helium-3.
What elements has only 1 proton?
The element hydrogen has the simplest atoms, each with just one proton and one electron.
Which element has the most proton?
uranium
The heaviest element in nature is uranium, which has 92 protons.
Why are neutrons less than protons?
The existence and stability of atoms rely on the fact that neutrons are more massive than protons. The measured mass difference is only 0.14% of the average of the two masses.
What has fewer electrons than protons?
If an atom has the same number of electrons as protons, it is a neutral atom. If it has a net charge, (more or less electrons than protons) it is an ion. If it has fewer electrons than protons it has a net positive charge and is known as a cation.
How many protons are in the element?
Its atomic number is 14 and its atomic mass is 28. The most common isotope of uranium has 92 protons and 146 neutrons. Its atomic number is 92 and its atomic mass is 238 (92 + 146)….2.1 Electrons, Protons, Neutrons, and Atoms.

How many protons does neon have?
10
Neon/Atomic number
Neon is an atom with atomic number ten. Its atomic weight is 20.179 which cause it to have ten neutrons and ten protons in its nucleus and ten electrons outside. Neon; Neon, Ne, is a colorless inert noble gas and it is also the second lightest noble gas.
What is the lightest gas?
hydrogen
The atomic weight of helium is 4.003. The French astronomer Pierre Janssen discovered helium in the spectrum of the corona of the sun during an eclipse in 1868. Helium is the second most abundant element in the universe, after hydrogen. Helium has monatomic molecules, and is the lightest of all gases except hydrogen. .
Which is the lightest element in the periodic table?
Hydrogen
Hydrogen is the lightest element and exhibits the simplest atomic structure.
Is there only one element that has more protons than neutrons?
According to Wikipedia: Other than protium (ordinary hydrogen), helium-3 is the only stable isotope of any element with more protons than neutrons.
Is a proton heavier than a neutron?
The neutron is very slightly heavier than the proton, by about 0.1%, or 1.00137841887 according to the best measurements. The neutron, as it happens, has a little more mass (and thus energy) than a proton and an electron combined.
Why are there more neutrons than protons?
The reason is that protons, being charged particles, repel each other. As you get to heavier elements, with each new proton you add, there is a larger repulsive force. As the nuclei get larger, the neutron well gets deeper as compared to the proton well and you get more neutrons than protons.
What are some elements that have no proton or electron?
Protium, isotope of Hydrogen consisting of a proton and an electron would the frist thing that comes to mind. well…if we go beyond what we usually learn in school, there is also an element called Neutronium which is also called element zero. It has no proton or electron, only neutrons, i.e., it’s atomic number is zero.
Which element has 1 proton and 1 neutron?
Even though Hydrogen is the correct answer to which “element”, we must remember that technically, the correct answer is Protium. Protium is the isotope of Hydrogen that has 1 proton. The other two are Deuterium (1 proton, 1 neutron) and Tritium (1 proton, 2 neturons).
How many protons and electrons does hydrogen have?
Related Questions More Answers Below. Of course it is the first element, hydrogen. It has an atomic number of 1, which means it has 1 proton. As mentioned by Ethan Cardenas, in it’s neutral state, hydrogen has 1 electron, but it can gain or lose an electron to become an ion.
How many protons neutrons and electrons are there in Krypton?
Protons, neutrons and electrons of all elements are mentioned in the table below (You will get the List + Shell diagram of all the elements.) 36: Krypton has 36 protons, 48 neutrons and 36 electrons: 37: Rubidium has 37 protons, Roentgenium has 111 protons, 161 neutrons and 111 electrons: Bonus Gift for you:
