What is the atomic number in an atom?
Atomic number = number of protons as well as the number of electrons in an atom.
What are the atomic number?
The atomic number of an atom is the atoms number of protons. The number of protons is same as the number of electrons.
How do you tell the atomic number of an atom?
The atomic number of each element is on the periodic table. The elements are arranged on the periodic table in order of increasing atomic number.
What year was the atomic number discovered?
ATOMIC NUMBER YEAR IN WHICH IT WAS DISCOVERED? it was discovered in 1913 by British physicist Henry Mosely
How many protons electrons and neutrons does Si-29 has?
Silicon-29 has 14 protons (atomic number), 14 electrons if the atom is neutral, and 15 neutrons (mass number - atomic number).
The atomic number of atoms reveals the number of?
Atomic number tells you the number of protons. There is no need to define a standard state.
Chemists define gram atomic mass as the number of grams of An element numerically equal to the?
atomic weight
Identify the subatomic particle used to define an element and explain why this particle is used.?
no i cant answer it
What do notice on the atomic number of elements in a row as one goes to the right of the table?
The atomic number increases from left to right across a period (row). This is because the atomic number is the number of protons in the nuclei of the atoms of each element. No two elements have the same atomic number. It is the protons that define an element.
Why do all atoms of an element have the same atomic number?
The atomic number represents the number of protons in an atom's nucleus, which determines the element's identity. All atoms of the same element have the same number of protons in their nucleus, hence they all have the same atomic number.
What does the number of nucleus tell you about the element?
The number of the protons in the nucleus of a chemical element is equivalent to the atomic number; the atomic number define the position of this element in the periodic table (group, period). And from these we can suppose the chemical properties of this element.
How are atomic number and atomic mass related to atomic structure?
The atomic number tells how many protons are in the atom, and the atomic mass tells how many neutrons and protons are in the atom together. Like Oxygen has an atomic number of 8. It also has 8 protons. It's atomic mass is 16. It also has 16 neutrons and protons. Helium's atomic number is 1. It only has 1 proton. It's atomic mass is 1 because it doesn't have any neutrons.
What does the atomic weight mass number of an element represent?
The atomic weight, or atomic mass, of an element represents the average mass of its isotopes, weighted by their natural abundance. It is typically expressed in atomic mass units (amu) and reflects the total number of protons and neutrons in the atomic nucleus, which collectively define the mass number. While the mass number is a whole number indicating the total count of protons and neutrons in a specific isotope, the atomic weight accounts for the relative proportions of all isotopes of the element found in nature.
What term is used to define the way the mass of subatomic particles is described?
The atomic mass or mass of an atom is locaed at the bottom of a sqaure on the periodic table. The atomic mass= atomic number (protons/neutrons)+electrons. Enable to find the number of electrons you must
This element has an atomic number that is double the atomic number of silicon?
this elemnt has an atomic number that is double the atomic number of silicon?
What is the atom identity?
Atom identity refers to the unique characteristics that define a specific element, primarily determined by the number of protons in its nucleus, known as the atomic number. This atomic number dictates the element's chemical properties and behavior in reactions. For example, carbon has an atomic number of 6, meaning it has six protons, while oxygen has an atomic number of 8, indicating eight protons. The arrangement of electrons and the number of neutrons also contribute to the atom's identity, influencing its isotopes and reactivity.
What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
