True or false- all atoms of the same element have the same atomic number?

The expression true or false atoms is not correct. All atoms are true entities. Each isotope of an element has a different number of neutrons; the number of protons and electrons is constant for all the isotopes of an element.

Yes, various elements differ essentially in proton number and also in neutron number though the last with some exceptions.
Even within the same element atoms still might differ in neutron number. Ions of the elements differ in electron number as well.

∙ 11y agoYes, atomic number is the number of protons and thats how an element is defined. If you change the amount of protons thus changing the atomic number, it becomes an entirely different element.

True or false The number of neutrons is equal to the atomic number?
This would be false. The atomic number is equal to the number of protons and the neutrons are the number you add to protons to equal the mass number (to find round the atomic weight).
The number of neutrons is equal to the atomic number true or false?
False as a generalization but true for some isotopes. The atomic number is the number of protons in a nucleus, which may coincidentally be the same as the number of neutrons but is not required to be.
All the atoms of an element are the same true or false?
A piece of pure Iron contains only one type of atom (Iron atoms) but there is more than one atom in it.
What is element about 78 percent of the earth's atmosphere?
The element Nitrogen (N) makes up about 78% of the Earth's atmosphere. Nitrogen is a gas at room temperature and has the atomic number 7. Nitrogen is in Period 2 of the Periodic Table and is the first element in Group 15(5).
There are three atoms of iodine represented in the formula NaIO3?
false
Was Dalton's hypothesis that atoms are indivisible and all atoms of an element are identical?
That was part of his atomic theory. We know now that that part of his atomic theory was incorrect.
The number of atoms in a mole of an element depends on what the element is. true or false?
That would be FALSE. One mole of every atom contains the same number of atoms, and that number is 6.02x10^23 atoms.
The atomic number of isotopes is determined by the number of atoms. true or false?
False. Number of neutrons.
What are charged atoms of elements that have a unique number of protons and electrons?
Each atom of an element has the same number of protons which is unique for that particular element ( = atom number in the periodic system)
The atomic number for an element is the total number of subatomic particles?
False; the atomic number is the total number if protons in the nucleus only.
Is it true or is it false Electronegativity increases continuously as atomic number increases?
False, because the only element with the highest Electronegativity is hydrogen and the atomic number is 1.
True or false atoms of different elements have the same never of protons?
All atoms of the same element are the same.7) Isotopes are a family of atoms all of which have the same number of electrons, have the same number of protons in their atomic centers, but different numbers of neutrons.
An element is a substance composed of atoms that all have the same number of electrons?
No . all the atoms have same no of protones.....
True or false a molecule with more than one kind of atom will be listed on the periodic table?
The answer to this question depends on the unstated definition of "kind of atom". All atoms of one element have the same atomic number, which equals the number of protons in nuclei of the atoms. However, atoms of the same element may have different masses because of different number of neutrons in their nuclei.
In alpha decay the parent element and the daughter element can be different isotopes of the same element but in beta decay the parent and daughter element are always the same?
No. In both the cases the element would definitely change. As alpha particle comes out then the new element would have two less in atomic number where as in beta particle decay the new element will have one higher in atomic number.
Atoms of different elements have different number of protons true or false?
No atom has the same number of protons as another atom, unless both atoms are atoms of the same chemical element.
Is element in the periodic table are arranged from left to right in rows by increasing atomic number?
Elements on the periodic table are arranged by atomic number. This refers to the number of protons in the nucleus of that atom. Generally, atoms with higher atomic numbers will have a higher mass (due to more protons); however, the number of neutrons in the nucleus (isotopes of each element) will also affect the mass. An element with a lower atomic number but extra neutrons could have a higher atomic mass than an element with a higher atomic number. The atomic mass listed on the periodic table is an average of the naturally occurring distribution of isotopes of that element. For example, Cobalt (element #27) has an atomic mass of 58.9332 amu, whereas Nickle (element #28) actually has a lower atomic mass of 58.6934 amu.
