atoms in a group have the same number of valence electrons
Elements are made of one type of atom. Atoms are made of electrons, neutrons and protons
number of valence electrons
2
The atomic number which is equal to the number of protons or electrons in a neutral atom.
Atoms that tend to gain electrons are located on the far left side of the periodic table.
They use a Periodic Table.
Atoms are neutral on the Periodic Table. Ions consist of more or less electrons than atoms.

he read about it in the newspaper
Usually, electrons are more attracted to atoms of elements that are located farther to the right and closer to the top of the periodic table; they are closer to the oxygen atoms than they are to the carbon atom. ~Ayanna91~
No. Atoms differ in number of protons, neutrons and electrons.
Just so you know, the periodic table does not give any indication of how many electrons an atom has but 95% of sulfur atoms are neutral and so contain 16 electrons.
we use the periodic table because it helps us with the atoms and electrons it tells us the mass number atomic number and the symbol
by the vertical family (where it is located)
They are metals and tend to lose electrons.
The atoms located on the left side of the Periodic Table, like elements such as lithium, sodium, potassium, caesium, rubidium and francium. These elements lose an electron very easy. The common name of these is alkaline metals.But not only alkaline metals lose electrons easily. A basic rule is that elements located on the left side of the periodic table loses electrons, and those on the right side gets electrons.I'll try to explain this very fast. The periodic table is organized very well. Which number the element is tells you how many protons the atom has. The atom has as many electrons as protons.When we're talking about reactions between elements, the outer shell of electrons is important. The electrons of the atom are organized very well, in several "shells". Which horizontal line the element is placed on tells you how many shells the atom has, and the vertical line tells you how many electrons it has in the outer shell.What the atoms "want" in a reaction is to have full outer shells. The atoms located on the left side has very fewelectrons in the outer shell, and the atoms on the right has very many electrons in the outer shell. Therefore, the atoms on the left gives away electrons, and the ones on the right get electrons. This is also why the atoms located on the middle of the periodic table don't react so easily, and why the atoms on the very right side (the noble gases) don't react at all.
