The heaviest element in nature is
uranium
, which has 92 protons.
Which element has the largest number of neutrons?
The atom with the largest number of neutrons is a tie
between livermorium and tennessine
. Each of these atoms contain 177 neutrons.
What element has the number of protons?
| Element | Hydrogen | Symbol | H | Atomic No. | 1 | Number of Electrons in Each Shell First | 1 |
|---|
Which element is the largest element?
Thus, helium is the smallest element, and
francium
is the largest.
What element has more than 30 protons?
Zinc
atoms have 30 electrons and 30 protons with 34 neutrons in the most abundant isotope.
Which atom has the smallest number of neutrons?
Hydrogen-1
has the smallest neutron number, 0.
Which atom is the largest value?
Oganesson
has the highest atomic number and highest atomic mass of all known elements.
What element has 2 protons neutrons?
Helium
is the second element of the periodic table and thus is an atom with two protons in the nucleus. Most Helium atoms have two neutrons in addition to the protons. In its neutral state, Helium has two electrons in orbit about the nucleus. Model of a helium atom's nucleus with two protons and two neutrons.
Can you have 0 neutrons?
Explanation: Hydrogen has 1 proton, 0 neutrons and 1 electron. The Isotope of hydrogen that can have zero neutrons is called
Protium
. The other hydrogen isotopes are Deuterium(1 neutron) and Tritium (2 neutrons).

Is element 119 possible?
Density (near r.t. )
Ununennium
, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. … It is the lightest element that has not yet been synthesized.
What is the only element that has no neutrons?
ProtiumProtium
, the most common isotope of hydrogen, consists of one proton and one electron. Unique among all stable isotopes, it has no neutrons.
Which element has the largest EI?
The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus,
helium
has the largest first ionization energy, while francium has one of the lowest.
What is the highest energy level?
What is it meant by the highest occupied energy level in an atom? The highest occupied energy level in an atom is
the electron-containing main energy level with the highest number
.
What do you call the element from atomic number 57 71?
The elements from atomic number 57 to 71 are called
Lanthanides
. They are called lanthanides, since lanthanum is chemically identical to the elements in the sequence. … The lanthanides are between Barium and Hafnium.
