Atoms of the same element always have the same number of what?
All atoms of a given element have the same number of protons in a nucleus. It is the number of protons in an atom's nucleus that determines the elemental identity of any atom. Period.
What is needed for any given element?
An element is defined a "type of atom"; to be more precise, all the atoms in an element have the same number of protons (but not necessarily the same number of neutrons).
What does the last element in any period always have?
The last element in any period always has its outermost electron in the same type of atomic orbital, either an s or p orbital.
Which is a property of all atoms?
Which of these is always true of atoms? protons, electrons AND neutrons are always equal in number they are always bonded to another atom they always have a charge they are always neutral in elements
The mass of any two atoms of the same element is always the same?
The masses of any two atoms of the same element are not always the same. Atomic mass (the mass you see on the periodic table) is just a weighted average of all of the weights of all of the different isotopes of an element.
What is arsenics subatomic particles?
The same as for any other element.The same as for any other element.The same as for any other element.The same as for any other element.
Is calcuim a mixture?
Only of isotopes. Calcium is an element. No mixture of chemicals can ever be a single element. The atoms of any element, such as calcium, always have the same number of protons and the same number of electrons. The number of electrons in an atom is the same as the number of protons in that atom. Different Isotopes of an element have different numbers of neutrons in the nucleus, but this doesn't change any of the chemical properties.
what are the 4 points in Dalton's atomic theory?
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
Can the density of iron be 6.8 gml?
No. The density of any given solid is always the same. Therefore the density of iron will always be 7.87 g/ml.
How do you find the number of electrons in element?
The Atomic Number of the element is equal to the number of electrons. Also, the number of protons is also equal to the Atomic number; so the number of protons and electrons in any given element is the same!
Who propose that the tatio of masses of elements in any given compound is always the same?
J. L. ProustJ. L. Proust
Speed that is the same at any given time is?
Speed that is the same at any given time is uniform speed.
