How many daltons does one molecule of water have?
One molecule of water has a total molecular weight of approximately 18 daltons. This weight is calculated by adding the atomic weights of two hydrogen atoms (each 1 dalton) and one oxygen atom (approximately 16 daltons).
How many daltons does an element with 8 elecrtons and 8 neutrons and 8 protons have?
"Dalton" in this context has the same meaning as "atomic mass unit". Each proton and each neutron has one Dalton, while electrons have none. Therefore, the element in question has 16 daltons, and is in fact an atom of the most common isotope of oxygen, oxygen-16.
What is the smallest amount of an element?
The smallest part of an element that has the properties of that element is the atom.
What does it mean if an atom has no subscript in a chemical formula?
There is one atom of that element in the molecule.
If a substance is composed entirely of one type of atom it is known as a?
An Element is the substance consisting of only one type of atom
How many daltons does one molecule of water have?
One molecule of water has a total molecular weight of approximately 18 daltons. This weight is calculated by adding the atomic weights of two hydrogen atoms (each 1 dalton) and one oxygen atom (approximately 16 daltons).
What do the numbers mean on the periodic?
On the Periodic Table, there are two numbers for every element: the atomic number and the atomic weight. The numbers at the top of the square represents the number of protons present in the atom's nucleus of that element. This is called the atomic number. For example, the atomic number for the element Krypton is 36. That means that there are 36 protons in the nucleus. If there were not 36 protons in the nucleus of that atom, that would create the atom of a completely different element. For example, if one proton was to be removed from the nucleus of the atom for the element of Krypton that atom will be an atom of the element bromine. The number at the bottom of the square represents the number of particles present in the atom's nucleus of that element. This is known as the atomic weight. For example, the atomic weight for the element Krypton is 83.80.

How Difference atom and element?
atom and elements are different because one atom makes an element and a element is a pure substance and a atom is a basic particle
What distinguishes the atom of one element from the atom another element?
the number of protons

What is the smallest amount of an element?
The smallest part of an element that has the properties of that element is the atom.
What is the difference about an element and a compound?
Element's have only one atom, while compund's have more that one atom.
What does it mean if an atom has no subscript in a chemical formula?
There is one atom of that element in the molecule.
What element has the automatic number 43?
The atom with atomic number 43 is Technetium. One thing should be known. If looking at a periodic table this element doesn't have an atomic weight. This is because this atom has no stable isotope present and therefore an atomic weight cannot be calculated.
What is the smallest amount in an element?
The smallest quantity of an element is an atom.
