What guantities are always equal to an elements atomic number?
Mass
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
How can you get the mass number and atomic number of element?
The mass number of an element is equal to the sum of protons and neutrons in the nucleus, while the atomic number corresponds to the number of protons. These values can be found on the periodic table for each element.
Is there any relationship between atomic mass and number of proteins and electrons?
Yes, there is a relationship between atomic mass and the number of protons and neutrons in an atom. The atomic mass is approximately equal to the sum of the number of protons and neutrons in an atom, as electrons have negligible mass compared to protons and neutrons. The number of electrons in a neutral atom is equal to the number of protons, in order to maintain a balanced charge.
The mass number of an atom is equal to?
The mass number of an atom is equal to the sum of its protons and neutrons. It is represented by the symbol "A."
What guantities are always equal to an elements atomic number?
Mass
Is the atomic mass equal to the molar mass?
1. The molecular mass of a compound is the sum oh the atomic weights of the elements contained in the molecule of this compound. 2. The atomic number of an element is the number of this element in the Periodic Table of Mendeleev; the atomic number is equal to number of protons and electrons.
Is the atomic mass equal to the number of atoms in the elements?
The mass number of an isotope of an element is equal to its atomic mass number. However, the atomic weight of an element is a weighted average of the isotopes that occur in the element in nature. Because almost all elements have more than one naturally occurring isotope (if they have any), the atomic weights of most elements are not integers, as mass numbers always are.
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
What does the mass number?
By knowing mass number of the elements we can easily find out the number of neutrons presen in the nuclei.Physical properties of elements somewhat depends on mass number.
How can you get the mass number and atomic number of element?
The mass number of an element is equal to the sum of protons and neutrons in the nucleus, while the atomic number corresponds to the number of protons. These values can be found on the periodic table for each element.
What are the relative atomic mass and the atomic number?
Atomic number:- the number of a chemical element in the periodic table of Mendeleev- a number equal to the number of protons in the atomic nucleus- a number equal to the number of electrons in the neutral atomRelative atomic mass: the mass of an isotope expressed in atomic mass units(1 amu= 1/12 atomic mass of the isotope 12C).For chemical elements the term atomic weight is reccomended by IUPAC.
What is the number of grams of an element that is numerically equal to its mass in amu?
The number of grams of an element that is numerically equal to its mass in amu is one mole (Avogadro's number of atoms or molecules). This is because the atomic mass unit (amu) is defined based on the carbon-12 isotope where 1 amu is approximately equal to the mass of one proton or neutron. For most elements, one mole of atoms or molecules is numerically equal to their mass in grams.
Can the atomic number be multiplied by two then equal the atomic mass?
Not generally. For light elements this relation is often approximately true, but for heavier elements, the gram atomic mass is more than two times the atomic number, as the ratio of neutrons to protons increases with increasing atomic mass.
The formula mass of neon is equal to its?
The formula mass of neon is equal to its atomic mass in atomic mass units (amu). This is because neon, like all elements, exists as individual atoms and its formula weight is the same as its atomic weight.
Atomic mass is equal to what?
atomic mass unit is equal to one-twelfth of the mass of a carbon-12 atomic mass is equal to one-twelfth of the mass of a carbon-12Atomic Mass is equal to the number of protons and neutrons.
Is there any relationship between atomic mass and number of proteins and electrons?
Yes, there is a relationship between atomic mass and the number of protons and neutrons in an atom. The atomic mass is approximately equal to the sum of the number of protons and neutrons in an atom, as electrons have negligible mass compared to protons and neutrons. The number of electrons in a neutral atom is equal to the number of protons, in order to maintain a balanced charge.
