Atoms of elements in group (column 2 of the Periodic Table) have 2 electrons in their outer shell. They have a low electronegativity, which means the electrons are not strongly attracted to the protons in the nucleus when compared to the electrons in atoms of column 6 or 7. For this reason, group 2 elements easily form +2 ion when in the presence of group 6 or7 elements.

What is special about a period on the periodic table?
all elements in a period all have the same amount of shells example: all elements in period 1 has only 1 shell all elements in period 2 has 2 shells so the period number is the same as the number of shells in that period
What happens to the number of atoms in 1mol of each elements in the periodic table increase?
One mole of any element will have Avogadro number (6.023 x 1023) of atoms And this number remains the same for all elements.
What are all elements are mixtures of?
An element is composed of atoms all with the same proton number(they are the same type). The only way the atoms in an element can vary is in the number of neutrons they have.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
What is the key difference that causes atoms of one element to differ from the other atoms of all other elements?
The number of protons. This is given by the atomic number.
What is special about a period on the periodic table?

What is the correlation of a period number with the elements of that period?
all the elements in period 1 have one energy level, all the elements in period 2 have two energy levels, all the elements in period 3 have 3 energy levels... and so on
What are three facts about elements?
Elements are the building blocks of matter. All atoms of the same element have the same atomic number. The mass number of atoms of the same element can vary.
All of elements in period have same?
Number of Electrons.
Do atoms have neutrons in them?
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
Do all elements of the periodic table have the same type of atoms?
No. Atoms differ in number of protons, neutrons and electrons.
What happens to the number of atoms in 1mol of each elements in the periodic table increase?
One mole of any element will have Avogadro number (6.023 x 1023) of atoms And this number remains the same for all elements.
What are all elements are mixtures of?
An element is composed of atoms all with the same proton number(they are the same type). The only way the atoms in an element can vary is in the number of neutrons they have.
Do all elements have atoms and molecules?
All elements have atoms, but most do not form molecules.
Which kind of elements are made of atoms?
All elements are composed of atoms.
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
What is the relationship between atoms elements and compounds?
I believe...compounds are made up of two or more elements. Elements are made up of atoms.
