If the compound contains a metallic or hydrogen cation derived from a single atom, the symbol of that element is written first in the name of the compound. If there is more than one such cation, the symbol of the less electronegative one is written first. If her is no such simple cation, the formula of the less electronegative polyatomic cation is written first.

In a properly written chemical symbol what is the first figure?
A chemical symbol refers to a chemical element; the first letter of a symbol depends on the chemical element.
In a chemical formula for an ionic compound what is written first?
the metal
What is the chemical combination of symbols that represents a compound?
Each element is given a symbol (a letter or a pair of letters where the first one is always a capitol letter and the second one is always a small letter). For instance the letter for Hydrogen is an 'H' and for Oxygen is an 'O'. When describing the formula for a chemical compound you use these symbols to say what elements it is made of and you follow each element with a number if there is more than one atom of that element in the compound. For instance water is made of one atom of Oxygen and two atoms of Hydrogen and therefore its chemical formula is: H2O
What was the first periodic table?
Hydrogen is the first chemical element in the Periodic Table of Mendeleev.
How is an element represented in a chemical formula?
Each atom has its own elemental 'symbol' or 'formula', there are more than 92 elements: from number 1. Hydrogen (H) to number 92. Uranium (U). Examples: O for oxygen, C for carbon, N for nitrogen atoms.
Which ion is written first in the chemical formula for a binary ionic compound?
The cation is written first in the chemical formula for a binary ionic compound.
What is the element that is the first half of the chemical formula describing table salt the chemical symbol?
Sodium
In a properly written chemical symbol what is the first figure?

Are chemical symbols placed in a certain way in a chemical formula?
more electropositive element first, followed by electronegative elements
What is the chemical formula of the first carbohydrate molecule?
CHO is the element symbol if that's what you mean
When writing a chemical formula the (what type of ion) gets written first.?
Cations are written first. For instance, NaCl or H2O.
