What does the atomic number tell you about the atomic structure of any element?
An atom contains Protons, Neutrons and Electrons the atomic number is the protons and neutrons combined, the number of protons in the atom is equal to the total number of electrons in the atom which are aranged in the outer shells at 2,8,8,8,8 and so on to find the totoal number of protons in the neucleus of the atom you take the atomic mass and minus the atomic number from it. so He or Helium is 4.0026 atomic mass and 2 for atomic number and so has 2 protons and so in turn has 2 electrons.
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
What is inside the nucleus of an atom?
The nucleus of an atom contains neutrons and protons. Almost all of the mass in an atom is made up from the protons and neutrons in the nucleus. Because the nucleus is only made up of protons and neutrons, it is positively charged. Physicists believe that there is a cluster of Protons and Neutrons within an Atom's nucleus. Friend Premier is quite right. So instead saying inside the nucleus it would be apt to say that nucleus is made up of...
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
Center of atom?
The center of an atom is the atomic nucleus.
Mass number - atomic number?
The mass number represents the total number of protons and neutrons in the nucleus of an atom. The atomic number specifies the number of protons in the nucleus. The difference between the mass number and atomic number gives the number of neutrons in the nucleus.
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
Is atomic mass the amount of neutrons in the nucleus in the atom?
atomic mass = number of neutrons + number of protons.
The number of neutrons in the nucleus of an atom can be calculated by what?
The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.
What contributes to an atom's atomic number and to its mass number?
An atom's atomic number is determined by the number of protons in its nucleus, which are positively charged. The mass number is the sum of the protons and neutrons in the nucleus, as neutrons contribute to the atom's mass but not its charge.
Neutrons in the nucleus of an atom calculated?
Mass number minus atomic number = number of neutrons
The sum of protons and neutrons in the nucleus of an atom is the?
Atomic Mass. This can vary depending upon the number of neutrons in the nucleus. Whereupon it is known as an ISOTOPE. Do NOT confuse Atomic Mass , with Atomic Number(Z). The Atomic Number is an elements position in the Periodic Table, AND the number of PROTONS in the nucleus.
What are the differences between the atomic number and the mass number of an atom?
atomic no is the no of protones in a nucleus while atomic mass is the sum of protons and neutrons in nucleus of an atom....
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.
An atom of sulfur is represented by 3316S. How many neutrons are in the nucleus of this atom?
The number 33 in "3316S" represents the atomic number of sulfur, which is the number of protons in its nucleus. To find the number of neutrons, subtract the atomic number from the atomic mass. In this case, the atomic mass is 16, so there are 16 - 33 = 16 neutrons in the nucleus.
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.
Atomic mass is the number of what in the nucleus?
Atomic mass is the sum of protons and neutrons that are present in the nucleus While the number of protons and electrons remain constant in the neutral atom, the number of neutrons may vary within different atom species of the same element. As a result, the atomic mass for one atom may be different from another atom of the same element if the number of neutrons varies.
