What are the atomic numbers of boron?
The atomic number of boron is 5.
Why are the numbers ordered as they are on the periodic table?
The numbers on the periodic table, known as atomic numbers, are ordered based on the number of protons in an atom's nucleus. This arrangement follows a pattern that groups elements with similar properties together. The atomic number increases from left to right and top to bottom across the periodic table.
Do Isotopes of uranium have different atomic numbers?
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
What are the big numbers called on the periodic table?
The big numbers on the periodic table are called atomic numbers. They represent the number of protons in the nucleus of an atom, which determines the element's identity.
What is the atom with same atomic number but different mass number?
Isotopes are atoms with the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers. For example, carbon-12 and carbon-14 are isotopes of carbon.
What is a non example of a atomic number?
Only the counting numbers can exist as atomic numbers. Fractions and decimals cannot be an atomic number.
How atomic structure forms a bond?
It depends on the atomic number. For example some atomic numbers create oxygen and others create metal such as zinc.
How do you write atomic numbers in symbolic notation?
Atomic numbers are written as a subscript to the left of the symbol of the element. For example, the atomic number of carbon is written as 6C.
How are atomic numbers and protrons related?
The atomic number of any element is equal to the number of protons in its nucleus. For example, fluorine (F) has an atomic number of 9. This means it has 9 protons.
How can you figure the numbers of neutrons in an atom?
You subtract the atomic number from the atomic weight. For example, if you have a helium atom and its atomic weight is 4 and you subtract its atomic number (2) the number of neutrons in the helium atom is 2.
What is a example of a non atomic number?
An example of a non-atomic number is 1/2 as it is a fraction and not a whole number.
Where are these numbers found in the periodic table?
There are multiple numbers on the periodic table. The ones right under the abbreviations is the atomic weight of the atom. The number just above the abbreviation is the atomic number. Here is an example: Sodium 11= Atomic Number Na= Atom Abbreviation 22.99= Atomic weight
What element has the atomic number for 3.14?
There is no element with the atomic number 3.14. Atomic numbers are whole numbers that represent the number of protons in an atom's nucleus.
What do the numbers on the periodic table mean?
On the periodic table, there are two numbers for every element: the atomic number and the atomic weight. The numbers at the top of the square represents the number of protons present in the atom's nucleus of that element. This is called the atomic number. For example, the atomic number for the element Krypton is 36. That means that there are 36 protons in the nucleus. If there were not 36 protons in the nucleus of that atom, that would create the atom of a completely different element. For example, if one proton was to be removed from the nucleus of the atom for the element of Krypton that atom will be an atom of the element bromine. The number at the bottom of the square represents the number of particles present in the atom's nucleus of that element. This is known as the atomic weight. For example, the atomic weight for the element Krypton is 83.80.
What is oxide atomic number?
The atomic number of oxide depends on the specific element it is composed of. For example, the atomic number of oxygen, which commonly forms oxides, is 8. Other elements forming oxides will have their own unique atomic numbers.
How is the mass of electons measured?
Example: Helium: Atomic Number; 2. Atomic Mass; 4.00 The electrons are the amount of protons in the nucleus. To find the protons you subtract the atomic number by the atomic mass. If the atomic mass consists of multiple numbers, round it up to the nearest whole.
What do the numbers mean on the periodic?
On the Periodic Table, there are two numbers for every element: the atomic number and the atomic weight. The numbers at the top of the square represents the number of protons present in the atom's nucleus of that element. This is called the atomic number.

For example, the atomic weight for the element Krypton is 83.80.
