Can 2 elements have the same atomic number?
No, because each element has its own specific property, BUT certain elements have similar properties, like elements in the same family. Meaning each element has more protons in their atoms than the previous.
Can two elements have same number of electrons?
Basically no two elements have same atomic number. Same number of protons and electrons are present in atoms which are in ground state. Example: Li is the third element in the periodic table, it’s atomic number is same as it’s number of electrons and protons which is 3.
Do elements have the same number of protons as electrons?
The atomic number is the number of protons in an atom of an element. Atoms must have equal numbers of protons and electrons. In our example, an atom of krypton must contain 36 electrons since it contains 36 protons. Electrons are arranged around atoms in a special way.
What does it mean when they have the same number of protons?
atomic number
An element’s atomic number is equal to the number of protons in the nuclei of any of its atoms. The mass number of an atom is the sum of the protons and neutrons in the atom. Isotopes are atoms of the same element (same number of protons) that have different numbers of neutrons in their atomic nuclei.
How many elements have the same number of protons?
All atoms of an element have the same number of protons, and every element has a different number of protons in its atoms. For example, all helium atoms have two protons, and no other elements have atoms with two protons….Atomic Number.
| Name | Helium |
|---|---|
| Neutrons | 2 |
| Electrons | 2 |
| Atomic Number (Z) | 2 |
| 4 |
What two elements have the same atomic mass?
Atoms of an element with the same mass number make up an isotope of the element. Different isotopes of the same element cannot have the same mass number, but isotopes of different elements often do have the same mass number, e.g., carbon-14 (6 protons and 8 neutrons) and nitrogen-14 (7 protons and 7 neutrons).
Which elements have same number of protons and neutrons?
Helium and Carbon are two elements with same number of protons and neutrons.
Is it possible for two or more elements to have the same number of protons Why?
Explanation: Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number.
Do elements always have the same number of protons and neutrons?
Atoms of a particular element must have the same number of protons but can have different numbers of neutrons. When an element has different variants that, while all having the same number of protons, have differing numbers of neutrons, these variants are called isotopes.
How can these two atoms have the same atomic mass?
Assuming you just mean the mass of the atom, it means that they have a different number of neutrons. Otherwise, all atoms with the same atomic number have the same atomic mass.
How many protons are in each element?
For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28. The most common isotope of uranium has 92 protons and 146 neutrons. Its atomic number is 92 and its atomic mass is 238 (92 + 146)….2.1 Electrons, Protons, Neutrons, and Atoms.
| Element | Hydrogen | |
|---|---|---|
| Symbol | H | |
| Atomic No. | 1 | |
| Number of Electrons in Each Shell | First | 1 |
Can atoms from two different elements have the same number of protons?
Explanation: Atoms from two different elements may have the same number of neutrons, but never the same number of protons. The number of protons is unique to the element and represents the atomic number. For example, you can look at radioactive decay. Uranium-238 decays and loses alpha and beta particles.
What happens when you add a proton to an atom?
Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom. Hereof, which elements have the same number of protons?
Do isotopes of the same element have the same mass?
These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses. Mass is the word for how much substance (or matter) something has. Click to see full answer.
Is there any element with the same number of protons as sulfur?
No, there can be no other element that has the same number of protons as sulfur, and that is because elements are defined by the number of protons that they have. Therefore no two elements can have the same number of protons; if they did, they would be the same element.
