Two of them. A group 2 element has two valency electrons whereas those in group 17 have 7. The latter need one electron to make an ionic bond so two of them can react with a single group 2 element.

When the atoms of the elements of group 0 are compared in order from top to bottom the attractions between the atoms of each successive element?
increase
What additional information is needed to calculate the molecular formula from the percent by mass of each element in a compound?
The number of atoms of one element in the compound
What is the substance made up of atoms?
The atoms of an element are all identical.
The measure of the number of atoms in one element that will combine with an atom of another element is?
These atoms are known as valence atoms.
Explain the relationship among atoms elements and compounds-?
Atoms are the smallest particle of matter. Each has a nucleus of protons and neutrons surrounded by electrons. An element is an atom with a particular atomic number, that is, a certain number of protons. Each element has a different number of protons. A compound is something formed by two or more atoms.
Can an element be a group of atoms?
yes
What element in Group 1 has the largest atoms?
Francium
Is aluminium a mixture or a compound or an element Explain the question?
Aluminium is a chemical element because all atoms are identical.
Groups of atoms joined together form?
a group of the same attoms create an element and a group composed of different atoms forms a compound
Atoms of element that are in the same group have the same number of?
valence electrons
Which element has the heaviest atoms from the group calcium fluorine uranium?
Uranium
Why do elements consist of atoms?
Elements are just one type of atom. An element is a group of atoms of one type.
Element X exists as a nonpolar molecule made of two identical atoms When individual atoms of element X react with sodium they form ions with a 2- charge What group does element X belong?
Group: The Oxygen Family and has 6 valence electrons.
When the atoms of the elements of group 0 are compared in order from top to bottom the attractions between the atoms of each successive element?
increase
How many atoms of each element are needed to form one molecule of water?
at least two
What is special about an element?
All substances are made of tiny particles called atoms. An element though, contains just one type of atom. So all atoms of the element gold are alike :) hope this helps!
What additional information is needed to calculate the molecular formula from the percent by mass of each element in a compound?
The number of atoms of one element in the compound
