Does each element have a unique atomic number?
Yes, each element has a unique atomic number, which is determined by the number of protons in the nucleus of an atom of that element. The atomic number is what distinguishes one element from another on the periodic table.
What does an element number mean on the periodic table?
The element number on the periodic table corresponds to the number of protons in the nucleus of an atom of that particular element. This number is also known as the atomic number and defines the identity of the element. Elements are arranged on the periodic table in order of increasing atomic number.
What are the names and atomic numbers of the halogens?
Fluorine = 9 Chlorine = 17 Bromine = 35 Iodine = 53 Astatine = 85
Is oxygen a noun?
Yes, it's the name of an element. All names of people, places and things are nouns.
How can the atoms name be determined?
The name of an atom is determined by the number of protons it contains in its nucleus. This number is called the atomic number and is specific to each element. Each element has a unique name that corresponds to the number of protons in its nucleus.
Does each element have a unique atomic number?
Yes, each element has a unique atomic number, which is determined by the number of protons in the nucleus of an atom of that element. The atomic number is what distinguishes one element from another on the periodic table.
Where is mass number and atomic number when an element is represented in symbolic way?
Answer potassium is number 19The atomic number, the number of protons in an element, is shown at the bottom left hand corner of the element, whereas the mass number is shown at the top left hand corner of the element. The mass number shows the number of protons+neutrons in the element

What can we find on the periodic table?
The Periodic table is a table with more than a hundred Elements on it. As of 2010, there are 118. Along with the names of the Elements there is the chemical symbol of the Element, the atomic number, and usually the atomic mass of the Element. The atomic number represents the number of Protons in one atom, and the atomic mass is the mass of the Protons and neutrons added together. The Electrons are not added onto the mass of the Protons and Neutrons because the Electrons are negligible.
Why were the atomic bombs given nick names?
That's a pretty stupid question given that these nick names were not given by the government but by the soldiers having fun.
On the periodic table what is the name for 254?
There is no element 254. Elements are identified by their names and by their atomic numbers, the number of protons in the nucleus. Atomic numbers do not go up much past 110, if that far. However, element 99, Einsteinium, does have an atomic mass of 254, which describes the total number of protons and neutrons in its most common isotope. Perhaps that is what you mean.
How are elements represented on the Periodic Table of Elements?
Every element on the periodic table is made of a number of protons and neutrons in the center with electrons around them. What makes one element different from another is the number of protons it has. The number of protons an element has is equal to that element's number on the periodic table.So, for example, Helium, which is element #2, has two protons. Oxygen, element #8, has 8 protons.The element's number that is also its number of protons is the small whole number located above the element symbol. E.g. 8 is written above O for oxygen. (The larger decimal number below the element symbol is something different, the average mass of the element.)
Does the person who names and element have to get it approved by everybody?
Nowadays, UIPAC decides whether a name given to an element will become the standard or not. Generally, they have been giving names based on the element's number. A science teacher of mine tells me that this was originally to settle disputes between groups of people who thought they had discovered an element "first".
How many neutrons are there in an atom of uranium whose mass number is 235?
Like all isotopes of uranium (identified by the "mass number" following the element name--235, in this case), U 235 has the atomic number 92. An element name is really just a more memorable way to designate a specific atomic number. This is because different isotopes with the same atomic number such as U 238 (the common type) and U 235 (a rare type)--or, to take a more common example, Carbon 12 (the common kind) and the slightly radioactive Carbon 14 (extremely rare), share the same number of electrons with all weights of the element. To put it another way, an isotope identified by a mass number (235 or 238) is just a slightly leaner or heavier version of the same atomic number. So, even though U 238 has three more neutrons in its nucleus than does U 235, the two have the same atomic number; which is just another way of saying they are the same element. The number of electrons determines how an element behaves chemically and that's how element names are assigned. Elements are sorted by chemical interaction characteristics, not by weight: weight. The mass number (in this question, 235) is a subdivision of element/atomic number. If an element has the same name, but a different mass number, all elements with that name share the same atomic number.
What is the element names after Thor the Scandinavian god of war?
The element named after Thor is thorium. It is a naturally occurring radioactive metal with the symbol Th and atomic number 90. It is named after the Norse god Thor due to its strength and power.
