What are other differences between lithium and helium?
Helium has an atomic mass of 4.- Number of Protons/Electrons: 2- Number of Neutrons: 2Lithium has an atomic mass of 7.- Number of Protons/Electrons: 3- Number of Neutrons: 4Helium has TWO less neutrons than Lithium.
Which subatomic particles contribute the most to the mass of potassium?
The protons and neutrons contribute the most to the mass of potassium. Protons have a positive charge and determine the element's identity, while neutrons provide additional mass without affecting the charge. Electrons have negligible mass compared to protons and neutrons.
Why can't the mass number be smaller than the atomic number?
The mass number has to be greater then the atomic number because the mass number is the protons plus the neutrons. If you were to take 10-12 you would get a negative number of 2 and there can't be a negative number of neutrons!
What particles make up the mass of the atom?
Protons and neutrons, the particles that make up atomic nuclei, are the ones responsible for almost all of the mass of an atom. As the electron has less than 1/1800th the mass of a proton, a whole flock of electrons won't significantly change the mass of an atom. We look to the protons and neutrons (called nucleons when they are being considered as components of an atomic nucleus) to contribute to the mass of an atom, and they will be considered when we derive the atom weight of an element.
Who has the smallest mass electrons protons or neutrons?
Of the neutron, proton, and electron, the electron has the smallest mass.
Have about 1800 times less mass than protons and neutrons?
Electrons have ~1800 times less mass than protons and neutrons
What is a noble gas with a mass of less than 15?
Helium
What element has 48 neutrons and a mass less than 100?
Cadmium atomic number is 48. so, it can have 48 protons and neutrons and electrons each. it has mass less than 100. 96cadmium has 48 protons and 48 neutrons. 96 means its mass i.e, number of protons and number of neutrons
What differentiates each subatomic particle?
The mass and the charge. Protons are positively charged. Electrons are negatively charged. Neutrons have no charge. Protons and neutrons have similar mass (about 1 amu). The mass of electron is about 1822 times less than that of protons / neutrons.
Wich two subatomic particles have about the same mass?
Protons and neutrons have about the same mass. Protons and neutrons both have a mass of 1.67*10-27 kg, the last one being less than 0.2% heavier than a proton (at rest).
What elements mass is 30 and a noble gas but not neon?
The element with a mass of 30 and is a noble gas, other than neon, is krypton (Kr). With an atomic number of 36, krypton has 36 protons in its nucleus and typically has 44 neutrons in its most common isotope, giving it an atomic mass near 84.
How much of an atom mass does the nucleus make up?
I believe that in gold atoms, 99.994% of the mass comes from its nucleus. Electrons way thousands times less than neutrons and protons, and since the protons/neutrons are nucleons the mass comes from the nucleus.
The atomic mass of iodine is less than the atomic mass?
The atomic mass of iodine is about 126.9 g/mol, which is indeed less than the atomic mass of many other elements. This low atomic mass for iodine is due to its position in the periodic table and the number of protons and neutrons in its nucleus.
Why atomic mass is always greater than atomic number?
Atomic mass includes the total mass of protons, neutrons, and electrons in an atom. Since protons and neutrons contribute significantly to the mass of an atom, atomic mass is generally greater than atomic number, which represents the number of protons in the nucleus. Electrons have a much smaller mass compared to protons and neutrons, so they have less impact on the overall atomic mass.
What contributes to the most of the mass of an atom?
The majority of the volume in an atom is filled by the neutrons and the protons. Although the electrons do have a volume, they occupy significantly less space than the other two subatomic particles
What are other differences between lithium and helium?
Helium has an atomic mass of 4.- Number of Protons/Electrons: 2- Number of Neutrons: 2Lithium has an atomic mass of 7.- Number of Protons/Electrons: 3- Number of Neutrons: 4Helium has TWO less neutrons than Lithium.
What element has a mass of less than 30 and is a noble gas?
The element with a mass of less than 30 and is a noble gas is Neon (Ne). Neon has an atomic mass of around 20.18 and is a colorless, odorless gas commonly used in neon signs due to its bright red-orange glow when electrified.
