A piece of pure Iron contains only one type of atom (Iron atoms) but there is more than one atom in it.
No, they are totally different elements with different numbers of proton and electron.
No there are different number of protons, neutrons, and electrons
True.
compounds are made up of atoms of different elements
true
False
False
True
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.
true
You think probable to isotopes: atoms of the same element but with different number of neutrons.
No,. The halogens will gain 1 electron when they react if electrons are exchanged.
True
No . all the atoms have same no of protones.....
That would be FALSE. One mole of every atom contains the same number of atoms, and that number is 6.02x10^23 atoms.
No. This is a definition of an atom. Electrons are only part of atoms.
True apex
No atom has the same number of protons as another atom, unless both atoms are atoms of the same chemical element.
false
This affirmation is false.
FALSE
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.
Yes, it is true.
nO
- A molecule may contain different types of atoms.- An element can be composed from different isotopes.
