The atomic number is the number of protons in the nucleus. Neutral atoms contain the same number of electrons as protons to balance the electrostatic charge.
The number of electrons on an atom will determine its charge, loss of electron(s) will make it positive, gain will make it negative. This occurs when atoms form ions.

What is He2s1?
He2s1 is a chemical notation for a helium atom that has one electron in the 2s subshell. This notation is commonly used to represent the electron configuration of an atom.
What is implied when there no subscript on a element?
When there is no subscript on an element, it is implied that one atom of that element is present. For example, "H" would represent one atom of hydrogen.
How do you make ball and stick model of methane?
To make a ball and stick model of methane, you would need four small balls to represent the carbon atom and the hydrogen atoms and four short sticks to represent the chemical bonds. Attach a stick to one ball to represent the carbon atom, then attach three sticks, each with a ball at the end, to represent the hydrogen atoms bonded to the carbon atom. Arrange them in a tetrahedral shape with the carbon atom in the center and the hydrogen atoms at the corners.
In an electron dot diagram the symbol for an element is used to represent?
In an electron dot diagram, the symbol of an element is used to represent the nucleus and inner electrons of the atom. The dots surrounding the symbol represent the outermost electrons, or valence electrons, of the atom.
Is the The oxidation number of an atom is shown with a subscript?
No, the oxidation number of an atom is typically written as a superscript, not a subscript. It is denoted next to the symbol of the atom to represent the charge that the atom carries in a compound or ion.
What are letters used to represent an atom?
A symbol.
What does an atomic number represent in an atom?
the elementprotons in the nucleuselectrons in the electron cloud of a neutral atom
In Thomas plum pudding model of the atom the plugs represent?
The plugs represent the electrons.
What does the number of protons represent?
positive charge in the atom
In Thomson and plum-pudding model of the atom the plums represent?
The plums represent negative electrons
What does atomic mass represent of an element represent?
Atomic Mass represents the mass of atom. We use mass of protons and neutrons.
In a model of an atom what would this symbol represent?
You think probable to the chemical symbol of an element.
Is it true that an atom is made up of two or more chemicals?
No, an atom may only represent one element. It is pure.
How do the circles represent the different parts of an atom?
They don't, unless you mean the smaller ones on the larger ones. The larger, uncoloured circles represent the orbital paths of the electrons of the atoms. The smaller, coloured circles represent the different parts of the atom, like the protons, neutrons, and electrons.
Why is bigger circle used to represent an atom of uranium?
because it has more electrons
What is He2s1?
He2s1 is a chemical notation for a helium atom that has one electron in the 2s subshell. This notation is commonly used to represent the electron configuration of an atom.
