What is a chemical element?
A chemical element or element is a species of atoms having the same number of protons in their atomic nuclei (i.e. the same atomic number, or Z). Therefore, the elements can be listed by the number of protons in the atom of each element as listed below.

Why is science the most reliable way to answer questions?
It’s the most reliable way to answer questions on how our Universe works. It cannot answer moral or existential questions, those matters are not within the interests of science. Therefore “scientism”, the idea that all questions can be answered by science (not the idea that science is unreliable, quite the contrary), is nonsense.

What are the symbols on the periodic table of elements?
However, the Periodic table generally displays only the symbol of the element and not its entire name. Most of the symbols are similar to the name of the element but some symbols of elements have Latin roots. An example for this is silver which denoted by Ag from its Latin name “Argentum”.

What is the atomic mass of the first 20 elements?
Atomic Mass of First 20 Elements The atomic mass of a solitary atom is just its absolute mass and regularly expressed in atomic mass units or amu. By the definition, the carbon atom with six neutrons, denoted as carbon-12, has an atomic mass equal to 12 amu.

Why should we not consider the facts of science scientism?
Science is those most reliable method of getting close enough to truth to make practical use of the information obtained that humans have invented or discovered so far. Science isn’t a source of truth at all its a source of fact. Truth is a philisophical concept not a scientific one. And no we shouldn’t consider the facts of science scientism.

What is the atomic number of an element?
Atomic mass is always measured using the atomic mass unit (amu). The atomic number is simply a digit which is used for placing the elements in the periodic table. Is this page helpful? 1.

How do you memorize the first 20 elements in chemistry?
– H You can devise your own way of memorizing the first 20 elements. It may help to associate each element with a name or a word that makes sense to you. Here are the names and symbols of the first elements. The numbers are their atomic numbers, which is how many protons are in an atom of that element.
