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.
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
What happens to an atom in terms of atomic mass and weight when it loses one particle?
If an atom looses an electron, neither the atomic mass nor atomic weight change appreciatively. If it looses a proton or neutron, both atomic mass and atomic weight decrease by one and it becomes an atom of a different element (on loss of a proton), or a different isotope of the same element (upon loss of a neutron).
What is a atomic number in a element?
The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
What Elements contain only one type of atom?
By definition, an Element contains only one kind of atom - atoms of that element. If it has more than one kind, it is a compound, not an element.

How many elements are in a atom?
i don't know about 2
What do the numbers mean on the periodic table?
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 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 difference about an element and a compound?
Element's have only one atom, while compund's have more that one atom.
