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.
How many protons are in Lead 204?
This is actually a very, very easy question to answer. Now, all atoms of the same element have the same number of protons. Otherwise, they wouldn't be the same element. For instance, if lead had one more proton, it would be bismuth, a non-toxic shiny metalloid. If it had one less, it would be thallium: a deadly poison which was only recently found. Lead has 82 protons. When the number is given by an element name (e.g. lead-204), it is also showing the atom's nucleus' mass number. Natural lead contains lead-204, lead-206, lead-207, and lead-208. Each of these contains the same number of protons, but different numbers of neutrons, hence the mass difference. To find the number of neutrons, N, we subtract the number of protons, Z, from the mass number, A. So, 204 - 82 = 122. Lead-204 contains 122 neutrons.
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.

What has one less than protons than nitrogen?
This chemical element is carbon.
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
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 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.
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.
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.
