What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
What is the atomic number and number of valence electrons for each nucleic acid elements?
For carbon (C): Atomic number 6, 4 valence electrons. For hydrogen (H): Atomic number 1, 1 valence electron. For nitrogen (N): Atomic number 7, 5 valence electrons. For oxygen (O): Atomic number 8, 6 valence electrons. For phosphorus (P): Atomic number 15, 5 valence electrons.
How do you find number of valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
How the atomic number related to the core electrons?
The atomic number represents the number of protons in an atom's nucleus, which is also equal to the number of electrons in a neutral atom. Core electrons are those that are closest to the nucleus and are not involved in chemical bonding. The number of core electrons in an atom is equal to the difference between the atomic number and the number of valence electrons.
What is the difference between the atomic number an its atomic mass?
Atomic number is the amount of electrons. Atomic mass is the amount of protons and neutrons.
What is the difference between number of protons and neutrons and atomic number?
g
What is the difference between americium and neptunium?
Neptunium has the atomic number 93 and americium has the atomic number 95.
Uses of atomic number?
Atomic number helps in determining the valence state of an element.
What is an element with 20 neutrons?
Calcium-40: The atomic number of calcium is 20 and the number of neutrons is always the difference between the atomic mass and the atomic number.
Does the valence electrons equal the number of protons?
No, the number of valence electrons does not necessarily equal the number of protons in an atom. The number of valence electrons is determined by the group number of the element in the periodic table, while the number of protons is the atomic number of the element.
