What element has the atomic mass of 254 and 155 neutrons?
The element with an atomic mass of 254 and 155 neutrons is californium (Cf). Its atomic number is 99, meaning it has 99 protons. To find the number of protons, you can subtract the number of neutrons from the atomic mass: 254 - 155 = 99. Therefore, californium has 99 protons and 155 neutrons.
How many nuetrons does an einsteinium element have?
99 protons 99 electrons Number of neutrons = Atomic mass of an isotope - Atomic number of the element Einsteinium's atomic number is 99 but Es has 19 known isotopes.Einsteinium has 99 protons.
Can you determine the element just by the number of neutrons?
It is the number of protons alone that determines elemental identity. Period. Different atoms of the sameelement can have different numbers of isotopes, called isotopes, but the nature of the element itself - its chemical identity - is determined by the number of protons in the nucleus. Only that.
How do you name nuclide?
When you name a nuclide, you give two pieces of information: the element name, and the mass number. For example, uranium-235, plutonium-239, cesium-137, technetium-99, fluorine-18, galium-67, iodine-123.
Which element turns into liquid at 99 degrees Celsius?
Any chemical is melted at 99 0C.

What synthetic element has the fewest protons?
In chemistry, a synthetic element is a chemical element that does not occur naturally on Earth, and can only be created artificially. So far 20 synthetic elements have been synthesized (those with atomic numbers 99-118). so the answer is the element Ensteinium with atomic number 99.
How many electrons neutrons and protons are in the nucleus of einsteinium?
Einsteinium has 153 neutrons, 99 protons, and 99 electrons. It's atomic mass is 252 and its shells are 2, 8, 18, 32, 29, 8, 2. Its chemical symbol is Es. Einsteinium has 19 isotopes; each isotope has a different number of neutrons.
What is the number of protons in einsteinium?
There are 99 protons.
How many electrons are in the nucleus of einsteinium?
Einsteinium has 99 protons and 99 electrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element Einsteinium's atomic number is 99 but Es has 19 known isotopes.
On the periodic table what is the name for 254?
There is no element 254. Elements are identified by their names and by their atomic numbers, the number of protons in the nucleus. Atomic numbers do not go up much past 110, if that far. However, element 99, Einsteinium, does have an atomic mass of 254, which describes the total number of protons and neutrons in its most common isotope. Perhaps that is what you mean.
Can you determine the element just by the number of neutrons?
It is the number of protons alone that determines elemental identity. Period. Different atoms of the sameelement can have different numbers of isotopes, called isotopes, but the nature of the element itself - its chemical identity - is determined by the number of protons in the nucleus. Only that.
