As the atomic number rises one, one proton, one electron, and a variable amount of neutrons are added.
The number of protons
Protons
All of the elements in group 1 on the periodic table contain the same number of outer electrons as sodium, which is 1.
number of protons
Most elements contain a mixture of two or more isotopes.

Milk contains a number of different chemical compounds and a number of different elements making up those compounds. It does contain hydrogen, oxygen, and calcium as you state, but it also contains carbon, nitrogen, phosphorus, and smaller amounts of some other elements.
Because each chemical element has a different atomic structure and contain a different number of protons and electrons.
No, the number of protons defines what element an atom belongs to. If two atoms are of different elements then they have different number of protons.
Because different elements have different numbers of protons, which determines the atomic number.
Ammonium nitrate contain 3 chemical elements.
All of the elements in group 1 on the periodic table contain the same number of outer electrons as sodium, which is 1.
Elements contain only one type of atom (atoms with the same number of protons). Compounds contain more than one element, and thus contain atoms with different numbers of protons. Compounds can be converted into elements, but elements are not reducible to anything simpler (besides subatomic particles).
The number of electrons is different because they are bonded
number of protons
what term describes elements that contain the same number of valence electrons
No, a base can have many different elements forming it. Water already has two elements, oxygen and hydrogen, so anything aqueous solution adds to that number.
The number of elements that contain the same type of outer electrons as sodium is 11.
Because they contain only one type of atoms (with same number of protons).
