Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
If fluorine has an atomic number of 9 and an atomic mass of 19 how many electrons does fluorine contain?
The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
What number is the atomic mass equal to?
The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.
If an element has an atomic number of 45 and an atomic mass of 92 the number of protons it has is?
The atomic number always gives the number of protons or electrons. The neutrons are obtained by subtracting the number of protons from the atomic mass. In this example, since 45 is the atomic number, this element has 45 protons. since the mass is 92, the number of neutrons is 92-45= 47. However, this is not really true because the element with 45 as atomic number is rhodium and it has a mass of 103 u and hence a total of 58 neutrons.
Fluorine's atomic number is 9 and its atomic mass is 19. How many neutrons does fluorine have?
Answer is in the question itself. 19. Because atomic mass is nearly equal to the mass number of the atom. Mass number is always a round number that is natural number. The proton code for fluorine atom is 9. Mass number is the total number of protons and neutrons. So for mass number 19, the number of neutrons will be 19 - 9 = 10.
What is equal to the total number of protons and neutrons?
If you add the number of protons to the number of neutrons in an atom, you have calculated that atom's atomic mass.
Is the number of valence electrons equal to the number of protons?
No, the number of valence electrons is not always equal to the number of protons. The number of valence electrons is determined by the group number of an element on the periodic table, while the number of protons is the atomic number of the element.
Which number is equal to the number of protons in the atoms?
The number of protons is identical to the number of electrons when an atom is in a neutral state.
Does the atomic number of aluminum equal to the total number of atoms in aluminum?
No, the atomic number refers to the number of protons in an atom. There are 13 protons in an aluminum atom, hence the atomic number is 13.
Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.

What number is the atomic mass equal to?
The atomic mass of an element is equal to the sum of the number of protons and neutrons in its nucleus. It is not directly related to the atomic number, which represents the number of protons in an atom.
What does the number of electrons in an atom determine?
In a neutral atom the total number of electrons is equal to the number of protons and atomic number.
Is the mass number of an atom equal to the atomic number?
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.
Total of proton and neutron in a molecule?
The atomic mass of a molecule is equal to the number of protons plus the number of neutrons.
What do you notice about the atomic number and the total number of electrons in an atom of that element?
The atomic number is equal to the number of protons in an atom, which also corresponds to the number of electrons in a neutral atom. This means that the atomic number gives you the total number of electrons in a neutral atom of that element.
How do atomic numbers relate to the number of particles in an atom's nucleus?
Atomic Number = the Number of Protons in the nucleus, = The number of electrons ( in the neutrally charged atoms). Do NOT Confuse with Atomic Mass , which is the total number of protons AND neutrons in the nucleus.
