What describes an atomic number of an element?
The atomic number of an element is the number of protons in the nucleus of an atom of that element. It determines the unique identity of an element and its position on the periodic table. Elements with the same atomic number belong to the same element, while elements with different atomic numbers are different elements.
No two different elements will have the?
No two different elements will have the exact same atomic number. Each element has a unique number of protons in its nucleus, which determines its atomic number and distinguishes it from other elements.
Which elements atomic nucleus contains 11 protons?
Sodium
How are atoms of different elements similar and how are they different?
Atoms of different elements are similar in that they all contain protons, neutrons, and electrons. However, they are different in terms of their atomic number (number of protons), atomic mass (sum of protons and neutrons), and electron configuration, which determines their chemical properties.
What did Henry Moseley discover in science?
Henry Moseley discovered the concept of atomic number and its significance in organizing the elements in the periodic table. His work helped to establish a more accurate and systematic way of arranging elements based on their number of protons in the nucleus. This laid the foundation for the modern periodic table of elements.

No two different elements will have the exact same atomic number. Each element has a unique number of protons in its nucleus, which determines its atomic number and distinguishes it from other elements.
Does mendelevium have nucleus?
All the chemical elements have an atomic nucleus.
How do you identify a compound or an element?
Elements are pretty much defined by the number of protons in the nucleus. This number (the atomic number) defines the element. All the different elements have different numbers of protons in their nucleus.
Why the elements are different?
Elements are different because each element has a unique number of protons in its nucleus, which determines its atomic number. This atomic number gives each element distinctive chemical properties and behaviors. Additionally, elements have different arrangements of electrons in their atomic structure, further contributing to their differences.
How do you find the number of protons in an elements nucleus?
The number of protons in an elements nucleus is the same number at the atomic number.
Atoms of different elements are what?
Atoms of different elements are characterized by the number of protons they contain in their nucleus, which determines the atomic number and identity of the element. The arrangement and number of electrons in the electron cloud surrounding the nucleus also vary among elements. Additionally, different elements have unique chemical properties based on how their atoms interact with one another.
What does an elements atomic number tell about that elements?
Atomic number indicates the amount of protons present in the nucleus of an atom.
Why using only Hydrogen atom in atomic spectra?
There are spectrums for many other elements too.
Atomic number - what does it indicate?
The atomic number represents the number of protons in the nucleus of an atom. It determines the element's identity and its position on the periodic table. Elements with different atomic numbers have distinct chemical properties.
The atomic number of an element determines its?
The atomic number of an element determines the number of protons in its nucleus, which in turn determines its chemical identity. Elements with different atomic numbers have different properties due to their unique number of protons.
Which elements atomic nucleus contains 11 protons?
Sodium
