What is meant the atomic number of an element?
The atomic number of an element is the number of protons found in the nucleus of an atom of that element. It uniquely defines an element and determines its chemical properties. Elements are arranged in order of increasing atomic number on the periodic table.
What element is more likely to be found in an organic compound?
Carbon - the element that defines the chemical word "organic".
What is chemical symbols?
A chemical symbol is simply an abbreviated way of writing a particular chemical. The symbol is a much more convenient way of identifying each element. Some examples are "O" for oxygen and "H" for hydrogen.
In a properly written chemical symbol what is the first figure?
The first figure in a properly written chemical symbol represents the atomic number of the element, which is the number of protons in the nucleus of an atom. The atomic number defines the element's identity and determines its unique chemical properties.
What structural element do all isotopes of an element have in common?
All isotopes of an element have the same number of protons in their nucleus. This is what defines them as being the same chemical element. The number of protons determines the element's atomic number.
What identifies the number of protons in the nucleus of an atom?
The atomic number refers to the number of protons in an element.
What is the smallest unit of a element that still maintains the characteristics of the element?
The smallest unit of an element that still maintains its chemical properties is an atom. Each element is uniquely defined by the number of protons in its nucleus, which stays constant in all atoms of that element.
How many elements are in Si?
Silicon (Si) is a chemical element with an atomic number of 14. It has 14 protons in its nucleus, which defines its identity as silicon.
What is unique identifier of a chemical element determined by how many protons are found in the nucleus of an atom?
color energy
Does each element have its own type of atom?
no Yes, the number of protons and electrons is different for each chemical element and the number of neutrons is different for each isotope.
Is tungsten carbide and graphite the same element?
Technically no, since an element defines that it is a single atom. Tungsten Carbide is a chemical compound consisting of Tungsten and Carbon (W2C) and Graphite is a form of pure carbon
What must stay the same in order for the element to stay the same?
For an element to stay the same, the number of protons in its nucleus (atomic number) must remain constant. This defines the element's identity on the periodic table and determines its unique chemical properties.
