What is An element or number in a sequence?
An element in a sequence is one of the individual values appearing in the sequence. It is typically identified by its position in the sequence, often denoted by a subscript. The term "number in a sequence" refers to the value of a particular element within that sequence.
How do you know which one is the atomic number?
The atomic number of an element represents the number of protons in the nucleus of an atom. It is typically located above the chemical symbol of the element in the periodic table. The atomic number determines the identity of an element and its position in the periodic table.
How many atoms does an element have if it does not have a subscript?
No subscript suggests one atom, for example carbon monoxide - CO - each molecule contains one atom of carbon and one atom of oxygen. As opposed to carbon dioxide - CO2 - in which each molecule has one atom of carbon and two atoms of oxygen.
In a single replacement reaction?
one element replaces one element
On the periodic table does one box represent one element?
Yes, one box represents one element.
