Which of the following pieces of information about the element Lithium describes the atomic number only?
The number of protons.
What following statement best describes the number of neutrons in an atom?
it's equal to the difference between atomic number and atomic mass number
What pieces of information best describes the atomic number of an atom?
Atomic number = number of protons in an atom, and = number of electrons in an atom.
What is the atomic number of an atom with mass number 9 and 5 electrons?
The atomic number is the number of Protons The mass number is the number of Protons and Neutrons The number of Electrons always equals the number of Protons Therefore according to the above information the atomic number of the atom is 5 HOWEVER there is NO element with a mass number (atomic mass) of 9 with an atomic number of 5. You question is impossible to answer. Beryllium has an Atomic mass of 9.0122 and an Atomic number of 4 Boron has an Atomic mass of 10.811 and an Atomic number of 5
How do you find the number of neutrons protons and electrons in an atom if the atom is neutral?
The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number
Which of the following pieces of information about the element Lithium describes the atomic number only?
The number of protons.
Which of the following determines the identity of an element atomic number mass number atomic mass or overall change?
atomic number
What is the atomic number and atomic mass number of the element that is formed in the following nuclear reaction that takes place in the sun?
The atomic number is 2, and the atomic mass is 4 (helium)
The atomic number of an atom is equivalent to which of the following?
The atomic number of an atom is equivalent to the number of protons in its nucleus.
What following statement best describes the number of neutrons in an atom?
it's equal to the difference between atomic number and atomic mass number
What information does atomic number offer?
number of protons and electrons
What pieces of information best describes the atomic number of an atom?
Atomic number = number of protons in an atom, and = number of electrons in an atom.
What information would you need to find the atomic mass?
atomic number and its squrare
What information was used to assign the atomic number to a particular element?
The atomic number of an element depends on the number of protons in that element.
Which of the following equals one atomic mass number?
Atomic number: number of protons or electrons in a neutral atomMass number: sum of protons and neutrons in the atomic nucleusAtomic mass number is not a very correct expression.
What other information about a element can be determined from its atomic number?
The number of electrons.
What information does the periodic chart tell you?
Symbol Name Atomic Number Atomic Mass
