Daltons atomic theory stated that atoms?
atoms are indivisible,tiniest particles of matter. they combine in simple whole no ratios to form elements or compounds. they can neither be created, nor destroyed.
What are Dalton points in the 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.
How did John Dalton explain a chemical reaction using his atomic theory?
Three laws during Dalton's time were the law of definite proportions, law of multiple proportions and law of conservation of mass. According to law of conservation of mass, there is no loss of mass during any chemical reaction. Dalton's proposition that atoms are not destroyed or invented. The atoms merely realign themselves in a chemical reaction; so there is no loss of mass. According to the law of multiple proportions, when 2 elements form more than 1 compound, the different masses of one element that combine with the other element are connected to each other in small whole ratios. For example, in the case of nitrogen dioxide and nitrogen monoxide. One atom of nitrogen combines with one atom of oxygen for nitrogen monoxide. One atom of nitrogen combines with two atoms of oxygen for nitrogen dioxide. In the case of law of definite proportions, it is stated that a chemical compound always has precisely the same proportion of elements in terms of mass. According to Dalton's atomic theory, matter consists of atoms and one type of atom is allocated for each element. Compounds were actually combinations of various kinds of atoms in fixed ratios.
Why does ionization energy decrease down the family?
You question is not very clearly stated but I think I know what you are asking. As you go down the column of any family of elements in the periodic table, you move to increasingly heavier and larger atoms. Their outer electrons are therefore farther from the nucleus, and even though the nucleus is larger and has a larger positive charge, the increased distance is the predominant influence, making the outermost electrons less tightly bound, and therefore more easily ionized, with a lower ionization energy.
What has more power an atomic bomb or a nuclear missile?
The question you are asking is equivalent in many ways to asking "Which number is bigger 27 or 27?" as an atomic explosive and a nuclear explosive are generally considered the same. The only difference is a bomb is typically an explosive delivered by a manned airplane whereas the explosive warhead on a missile is delivered by either a rocket or an unmanned airplane called a cruise missile. Either one could be a higher yield explosive, or as I stated in the example at the beginning of this answer both could be identical.

John Dalton's atomic theory stated that atoms of the same?
According to John Dalton, all the atoms of a single element will have the same mass. This is the basis for the modern atomic theory.
What are the atomic number and atomic mass of the isotope Br 79?
The atomic number of any bromine atom is 35, and the atomic mass number is the number stated after the element name in the question, in this instance 79.
Where is the atomic number written?
The Atomic Number Is Located On The TOP Of The Element Symbol. So Example. 14<ATOMIC NUMBER> Si<Symbol> 28.086<Atomic Mass> Silicon <The Name> This Is The Correct Order Of An Element That Should Be Labeled.
Is an element's atomic mass measured in kilograms?
The atomic mass is usually stated in grams if in any unit other than simply atomic mass units. Anything expressible in grams is also expressible in kilograms, so the answer is yes.
What are consistent with Dalton's atomic theory as it was originally stated Why a Calcium and titanium atoms have the same mass?
The atomic weight of calcium is 40,078.The atomic weight of titanium is 47,867.----Dalton principles not accepted today:Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties. But: Isotopes of a chemical element are not identical.Atoms of different elements combine in simple whole-number ratios to form chemical compounds.But: From many time nonstoichiometric componds are known.3. Atoms cannot be subdivided, created, or destroyed.But: This is valid only for chemical methods.

What element has the atomic number of 88?
The element with atomic number 67 is Holmium (Ho). Holmium is a Lanthanide in Group 6 of the Periodic Table. Holmium has 67 electrons in 6 shells with 2 electrons in the outer shell.
What was Daltons atomic theory all about?
the structure of the atom
How did Thomson experiment change Dalton atomic model?
John Dalton stated "all atoms of a given element are identical"; discovery of isotopes by Thomson infirmed this old hypothesis.

How do you estimate the number of neutrons in the atoms of an element?
The number of neutrons in the nucleus of an atom of any isotope of an element is equal to the "atomic mass number", which is usually stated in a number immediately after a hyphen at the end of the element name in the name of the isotope, minus the atomic number. Because most elements have more than one stable isotope, the average number of neutrons in the mixture of isotopes of an element that occurs naturally is usually not an integer.
