When an alpha particle is emitted the nucleus of the original element?
An alpha particle is a helium-4 nucleus, and contains two protons and two neutrons. Therefore, the original nucleus will have two protons and two neutrons less. Its atomic number will be two less, and its atomic mass will be 4 less.
What element has half as many protons zinc?
The element that has half as many protons as zinc would be copper. Zinc has 30 protons, while copper has 29 protons. This means that copper has one less proton than zinc, making it the element with half as many protons.
Does a isotope of a element have more protons?
All isotopes of an element have the same number of protons, otherwise they would not be the same element. What varies is the number of neutrons, they can be more or less than in the stable isotope(s) of the element.
What has one less than protons than nitrogen?
This chemical element is carbon.
What is the atomic number and atomic mass of this element?
Atomic number is the number of protons. Atomic mass is (mostly) the sum of the masses of the protons and neutrons (more or less).
What alkaline earth metal has more protons then argon but less protons then krypton?
This chemical element is calcium (Ca).
What element has one less proton than gold?
Platinum(Pt) has 78 protons. Gold(Au) has 79 protons
Is a noble gas with 48 neutrons and a mass of less than a 100?
The noble gas with 48 neutrons and a mass of less than 100 is Krypton. It has an atomic number of 36, which means it has 36 protons in its nucleus. The total mass of Krypton is slightly less than 100 atomic mass units.

This chemical element is carbon.
Which element has 20 protons 20 neutrons and 20 electrons?
Calcium has 20 protons and electrons. The symbol for calcium is Ca and its atomic number is 20.
What element has 26 electrons 29 neutrons and 26 protons?
The element that has 26 electrons 29 neuetrons and 26 protons is Iron (Fe) The number of protons= electrons/atomic number
What element has more than 50 but less than 75 protons and is in group 17?
Any one element can ONLY have a single fixed number of protons. Th only element with a number of protons that sits between 50 and 75 in group 17 of the periodic table is Iodine (I), with 53 protons.
This element has one less proton then sodium?
The element with one less proton than sodium is magnesium. Sodium has 11 protons, while magnesium has 12.
Does Mg 2 contains 15 protons and 10 electrons?
No, the element with an atomic number of 12 is magnesium (Mg), which contains 12 protons and 12 electrons in a neutral atom. If Mg 2 refers to a magnesium ion with a 2+ charge, it would have lost two electrons, resulting in 10 electrons.
