The atomic number represents the number of electrons while the atomic mass represents the total mass of the protons and neutrons.

. Which statement best describes why an elements atomic number is different from its atomic mass. The atomic mass of an atom is the sum of the mass of its protons neutrons and electrons. Mass number is sum of protons and neutrons so number of neutrons in chlorine-35 is 18.

The atomic mass of an atom is the sum of the mass of its neutrons and electrons. B The nitrogen atom has a mass number of approximately 14 daltons and an atomic mass of 7. They have a large difference in valence electron number They have a large difference in atomic mass.

1 on a question. Observe the model of the atom above. The atomic number represents the number of protons neutrons and electrons.

A the number of protons in the atom B the number of electrons in the atom C the number of neutrons in the atom D the number of protons electrons and neutrons in the atom E the net electrical charge of the atom. Count of the total number of protons and neutrons in an atoms nucleus. D Atomic weight of an element is calculated by adding the masses of its protons and.

Which of the following is a correct statement concerning nitrogen. Isotope of chlorine-35 has mass number 35. They share electrons between them.

The atomic number represents the. They are in the same period in the periodic table. In 1913 Niels Bohr proposed a model that illustrates the locations of subatomic particles.

Atomic masses are an estimated average of the artificially produced isotopes. A Atomic weight is determined by the number of electrons in an atom of a given element. Atomic masses are determined relative to an O-16 standard.

A The nitrogen atom has a mass number of approximately 7 daltons and an atomic mass of 14. Which statement best describes the atoms of elements that form compounds by covalent bonding. The atomic mass of an atom is the same as the atoms atomic number.

Which of the following best describes the atomic number of an atom. Which statement best describes why an elements atomic number is different from its atomic mass. The atomic mass of every atom of an element such as carbon is exactly the same.

Atomic number also called proton number refers to the. The atomic number represents the number of electrons while the atomic mass represents the total mass of the protons and neutrons. C Atomic weight of an element is approximately equal to the mass number of its most abundant isotope.

It is a weighted average so common isotopes have a greater effect than uncommon ones. An atom has 11 protons 12 neutrons and 11 electrons. 1 point Atomic masses are determined relative to an H-1 standard Atomic masses are a weighted average of the naturally occurring isotopes.

C The nitrogen atom has a mass number of 14 and an atomic mass of 7 grams. While models of the atom have changed with new understanding the location of the subatomic particles in current models. What is the identity of the element.

Which statement describes atomic. The answer is. Atomic mass is the weighted average mass of an atom of an element based on the relative natural abundance of that elements isotopes.

B Atomic weight of an element is approximately equal to the number of protons in its nucleus.
