Which atom is composed of 16 protons 16 electrons and 16 neutrons?
sulfur (S) (b) By referring to a periodic table or a table of elements, we see that sulfur (S) has an atomic number of 16. Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32.
What atom has 16 protons neutrons and electrons?
The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Sulfur is 16….Summary.

Which of the following has 16 protons?
Sulfur has 16 protons, silicon has 14 protons, and gold has 79 protons.
What is the average atomic mass of a hypothetical element consisting of two isotopes one with mass 64.23 amu 26.0 %) and one with mass 65.32 amu?
So atomic weight will be 64.23 Into 26 by 100. Because they said 26 Plus 65.32 into 74 by 100. This will be 64.2.
What is element 16 on the periodic table?
Sulfur Sulfur – Element information, properties and uses | Periodic Table.
What has 16 protons and 15 neutrons?
Answer and Explanation: The element with 16 neutrons, 15 protons, and 15 electrons is phosphorus.
Which group would an element with 16 protons belong to?
The oxygen family, also called the chalcogens, consists of the elements found in Group 16 of the periodic table and is considered among the main group elements. It consists of the elements oxygen, sulfur, selenium, tellurium and polonium.
How do you find the atomic mass of a hypothetical element?
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

What is group 16 called?
chalcogen oxygen group element, also called chalcogen, any of the six chemical elements making up Group 16 (VIa) of the periodic classification—namely, oxygen (O), sulfur (S), selenium (Se), tellurium (Te), polonium (Po), and livermorium (Lv).
What element has 16 protons in its nucleus?
Sulfur has 16 protons, silicon has 14 protons, and gold has 79 protons.

Which part of the modern periodic table breaks down dobereiner’s law of triads?
A triad is a grouping of three elements in order of atomic mass. Dobereiner's Law of Triads deals with putting three elements in order of atomic weight. The average of the first and third elements' atomic masses is the atomic mass of the second element. This law breaks down with the sequence of manganese through zinc.
How do you calculate mass of protons neutrons and electrons?
Atomic mass is the sum of the masses of the protons, neutrons, and electrons in an atom, or the average mass, in a group of atoms. However, electrons have so much less mass than protons and neutrons that they don't factor into the calculation. So, the atomic mass is the sum of the masses of protons and neutrons.
How do you calculate mass number?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
Why are group 16 elements called?
-Group-16 elements are also called chalcogens. They are called so because most of the copper ores have copper in the form of oxides and sulphides. They also contain small amounts of selenium and tellurium. The ores of copper are called 'chalcos' in Greek.
What is the 16th element?
Sulfur – Element information, properties and uses | Periodic Table.
How many neutrons are there in an atom with 16 protons and a mass number of 34?
18 neutrons One atom of sulfur with an isotopic mass number of 34 has 18 neutrons. 34 (total) – 16 (protons) = 18 (neutrons).
Which species has 16 protons quizlet?
The element with 16 protons is sulfur, with the symbol S.
What is the only letter not appearing on the periodic table?
The letter "J" is the only one not found on the periodic table. In some countries (e.g., Norway, Poland, Sweden, Serbia, Croatia), the element iodine is known by the name jod. However, the periodic table still uses the IUPAC symbol I for the element.

Did dobereiner triads also exist in the columns of Newlands law of octaves compare and find out?
Yes, Dobereiner's triads also exist in the columns of Newland's octaves. For example, the second column of Newland's classification has the elements Lithium (Li), Sodium (Na) and Potassium (K), which constitute a Dobereiner's triad. Was this answer helpful?
Why did Dobereiner’s theory fail?
The main Limitation of Dobereiner's classification of elements was that he failed to arrange all the then-known elements in the form of triads of elements having similar chemical properties. Dobereiner could identify only three triads. He was not able to prepare triads of all the known elements.
How do u calculate mass?
One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass.
How do u find the mass number?
Together, the number of protons and the number of neutrons determine an element's mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.
How do you find neutrons?
For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. number of neutrons=40−19=21.
