It is called a chemical symbol.
An atomic symbol is a 1-, 2-, or 3-letter code that represents an element. If the symbol consists of one letter, like carbon (C), the letter is capitalized. If the symbol consists of two letters, like magnesium (Mg), the first letter is capitalized, but the second letter is not. The 3-letter codes are for elements that have been recently synthesized and have not been given a permanent name, and for elements that have yet to be synthesized, both of which are given temporary systematic names based on their atomic numbers. An example is element 115, with the symbol Uup, which is currently named ununpentium, which means one, one, five. Eventually this element will be given a permanent name with either a 1-letter or 2-letter symbol.
They are the abbreviation of the name of the element. Some of the names are taken from the original Roman names (e.g. gold=Aurium=Au), the accepted English name (e.g. Aluminum=Al) or the name of a famous person or place (e.g. Einstein=Einsteinium=Es). There are some like Tungsten=W (for Wolfram) that require a knowledge of the history of the material's discovery.
It stands for Hydro fluoride acid.Only 1st letter is capital in a symbol of an element.
Every element has a one or two (or three, if the element doesn't have an official name yet) letter symbol.
An element square consists of the element's name, symbol, atomic mass, and atomic number.
This is known as the chemical symbol for the element.
This is known as the chemical symbol for the element.
The letter or group of letters that represents an element is called its chemical symbol. Each element has a unique chemical symbol, typically derived from its name in English, Latin, or another language.
The abbreviation of an element's name is called its chemical symbol, which is a one or two-letter representation used to identify elements in the periodic table. For example, the chemical symbol for oxygen is "O" and for hydrogen is "H."

The chemical symbol for the element sodium consists of a first capital letter and a second non capital letter: "Na". The atomic number of sodium is 11. (The term "first symbol" used in the question has no particular meaning of which I am aware.)
Chemical symbol
An elemental symbol, or chemical symbol, represents an element and can be either a single capital letter or a combination of a capital and small letter. For example, the chemical symbol for carbon is "C" and for sodium is "Na".
O is the the symbol of the element oxygen.
The one or two letter short form is called the symbol for the element.
They are the abbreviation of the name of the element. Some of the names are taken from the original Roman names (e.g. gold=Aurium=Au), the accepted English name (e.g. Aluminum=Al) or the name of a famous person or place (e.g. Einstein=Einsteinium=Es).

A chemical element's abbreviation is called its atomic symbol. This is typically a one or two-letter representation of the element's name.
