beryllium has 4 protons and helium has 2 protons
The electron is located in a cloud-like orbital around the atom's nucleus. The orbitals are of different types indicated by the letters s, p, d, etc. An s orbital has spherical symmetry, but the other types are more complicated.
count the number of protons which will be equal to number of electron.
A Krypton atom has 36 protons and 36 electrons each.
Calcium has 20 protons and electrons and a number of neutrons different for each isotope..
Protons and neutrons provide the mass of an atom. Each different kind of element has a unique number of protons. For example: all hydrogen atoms have one proton. However, not all hydrogen atoms have the same mass. Some hydrogen atoms have no neutrons, one neutron, or two neutrons. Atoms of the same element (one proton) but different numbers of neutrons (different masses) are called isotopes of that element. All elements have isotopes. Some isotopes of elements are radioactive and are useful in medicine and energy applications (nuclear, for instance).
beryllium has 4 protons and helium has 2 protons
There are 92 naturally occurring elements in the periodic table of the elements. Each element differs from the next by the number of protons within its nucleus. Hydrogen has one proton. Helium as two. Next comes Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Flourine, and Neon, rounding out the first ten. Google "periodic table" for a complete list.
The number of protons varies for different elements. For example, Hydrogen has only one proton in each atom. That's what makes hydrogen hydrogen. If it had two protons, it would be helium. If there were no protons, then it wouldn't be anything.
Each atom of one specific element has the same number of protons. For example, Helium has 1 proton in every atom's nucleus. To find how many protons are in an elements atoms nucleus, look at the elements atomic number on the Periodic Table.
2 of each
Helium is an atom. Heavier elements have molecules.
Helium atoms do not contain different types of atoms. Each helium atom consists of two protons and two neutrons in its nucleus, with two electrons orbiting around the nucleus.
First, some background. Elements are formed in the bowels of stars that contain mostly hydrogen and helium. These hydrogen and helium atoms make new elements when they fuse together. (Ex. 2 helium atoms fusing together makes 1 beryllium atom because 2 electrons and 2 protons from each atom come together to create an atom with 4 electrons and 4 protons which is beryllium.) When the star explodes, these newly made elements are spread around the universe. Back to the question. Because mercury's atomic number is 80 and gold's is 79, in order for gold to be obtained, you would have to knock off 1 proton 1 electron and 3 neutrons. If i am not mistaken, this can in fact be done in hadron colliders but because of such small quantities of gold can be obtained from this, (about 1g per century) it is not a feasible option for obtaining gold.
The periodic number of an element signifies its number of protons. Hydrogen, the first element, has one proton. Helium, the second element, has two protons. Lithium, the third element, has three protons. I'm sure you can figure out the rest.
4 protons, 4 electrons and a variable number of neutrons (different for each isotope)
Elements differ from each other based on the number of protons in their nucleus, known as the atomic number, which determines their identity. Each element has unique properties and characteristics, such as atomic mass, electron configuration, and chemical behavior, that set it apart from other elements. The arrangement of electrons in the outer shell also plays a significant role in determining an element's reactivity and bonding capabilities.
It has 2 protons ,2 neutrons & 2 electrons.
