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.
If an atom of iodine gains one electron it will have the same number of valence electrons as which element?
The same number of valence electrons as xenon.
How are the element within a row different?
They have different numbers of valence electrons.
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.
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.....
What is the same for every element in the same period?
The number of electrons in its valence shell
Do elements in each group have similar characteristics?
Yes. Every element in a group has the same number of valence electrons.
What element has the same valence electron configuration as phosphorus?
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê
What element has the same valence electron configuration as phosphorus p?
The answer is nitrogen. Nitrogen is one example of an element that has the same valence electron configuration as phosphorus.Ê

That would be FALSE. One mole of every atom contains the same number of atoms, and that number is 6.02x10^23 atoms.
What element as the same number of valence electrons as As?
Silicon is the element. It is present in same group as C.
Atoms of element that are in the same group have the same number of?
valence electrons
What does the group number of a element tell about valence electrons?
All elements in the same A group will have the same number of valence electrons.
If an atom of iodine gains one electron it will have the same number of valence electrons as which element?
The same number of valence electrons as xenon.
How many valence electrons are in the element fluorine and do the same for chlorine and bromine?
The number of valence electrons is seven.
True or false a chemical is always the same thing as an element?
FALSE
What do elements in a group have in common?
The elements in the same group have the same number of valence electrons and hence similar chemical and physical properties.
