What year did Dalton say that Atoms of the same element exactly alike?
1803
All the atoms in every element?
neutral, with the number of protons equaling the number of electrons.
If all atoms in a sample of matter are alike that kind of matter is?
an element
Why are the atoms in an element exactly alike in some ways but may not be alike in other ways?
they all have same number of protons and electrons (in unionized form) but may have different number of neutrons.
Are atoms of the same element familiar?
yes because the atoms in the specific element have the same properties as that element. :D
Substance in which all atoms are alike?
A substance in which all atoms are identical is called an element.
What year did Dalton say that Atoms of the same element exactly alike?
1803
What are substances in which all atoms are alike?
A substance in which all atoms are alike is an element.
Dalton's atomic theory stated that every element was made of atoms that could not be subdivided atoms of the same element are like and?
atoms are made of protons, neutrons, and electrons.
Do All atoms of an element have to be exactly alike?
yes they do
When all atoms in a substance are alike the substance is a?
element.
The atoms of anyone specific element are always?
alike
How are 2 isomers alike and how are they different?
Two isomers will have the same chemical formula. In otherwords the same numbers of atoms of each element. Those atoms, however, will be arranged differently.
All the atoms in every element?
neutral, with the number of protons equaling the number of electrons.
Is it true that all particles are alike in elements?
No. All atoms of a given element are alike in the number of protons, which is the atomic number of an element. However, the number of neutrons in the nucleus can vary. Atoms of elements with the same number of protons but different numbers of neutrons are called isotopes. All atoms of a given element in their ground state have the same number of electrons as they do protons, but if they form ions, the number of electrons will increase or decrease, depending on the element, but the number of protons remains the same.
How are the isotopes of an element are alike and how are they different?
The isotopes of an element are alike in that they have the same number of protons, electrons, and the same chemical properties. The isotopes are different in that they have different numbers of neutrons and thus different atomic masses.
Daltons atomic therory?
In the 1800s John Dalton did some experiments and these are some of his magnificent work: * all elements are composed of atoms. atoms can not be divided or destroyed * atoms of the same element are alike * .atoms of different elements are not alike * the atoms of two or more elements can join together to form compounds
