Describe the number of valence electrons in each atom as you move down group 2 in the periodic table?
Every atom in Column 2 of a wide form periodic table has two valence electrons.
The electron number is where on a periodic table?
The atomic number is the number of protons in the nucleus of any atom of any element. Because all atoms are neutral, the number of protons = number of electons. So the atomic number is the number of electrons. You may be confusing an atom with an ion. Atoms of elements on the right side of the periodic table have a stronger attraction for electrons than atoms of elements on the left side, For example, when a chloride atom get close enough to an atom of Sodium, the electron in the outer shell of the Na atom will move to the outer shell of the Cl atom. Now the Cl atom has 17 protons and 18 electrtons making a -1 charged ion. The Na atom now has 11 protons and 10 electrons making a +1 charged ion. Elements in column 1 of the periodic table form +1 ions. Elements in column 2 of the periodic table form +2 ions. Elements in column 7 of the periodic table form -1 ions. Elements in column 6 of the periodic table form -2 ions.
What is methane in the periodic table?
the periodic table contains the 118 base elements, these react to form a varity of compounds methane is a compound produced when four hydrogen atoms and a carbon atom react
How many electrons does an atom have to have in the outer shell to not form chemical bonds?
8, except in the first row of the periodic table, which is 2.
Elements are arranged by atomic number in the what?
They form the periodic table of elemennts (the table of Mendeleev).

Is oxygen a molecule or an atom?
oxygen is an element on the Periodic Table of elements. This means that oxygen is an atom which could bond with another element covalently to form a molecule
Where is cation on the periodic table?
Periodic table consists of elements not cations. However group 1 and group 2 elements (left side of the periodic table) are elements which will form cations easily.

How many valence electrons does a single neutral chlorine atom have?
7, as does an atom of any halogen (element in column 17 of a wide form periodic table.)
What group of elements in the periodic table are most likely to be in the gaseous form?
Noble Gases, Group 8A

8, except in the first row of the periodic table, which is 2.
Elements are arranged by atomic number in the what?
They form the periodic table of elemennts (the table of Mendeleev).
What two kinds of atoms form a covalent bond?
The closer they are to the center of the periodic table, the more likely they are to form covalent bonds. The closer to the edges, the less likely.
What is the smallest atom having tetra-valency?
Carbon is the smallest atom having tetravalency. Note that carbon is the atom in the uppermost* period of a wide form periodic table that includes column 14, the column in which the most common valency is tetravalency, and in general atomic size is greater the lower in a periodic table that the atom appears.___________________________*This is the second period of the table as a whole; the first period includes only columns 1 and 18.
What group of elemets will most likely form an ion with a -1 charge?
The halogens, listed in column 17 of a wide form periodic table.
