in period 1, 2 and 3 the number reduces. In period 1 from 2 to 1. In period 2 and 3 it reduces from 8 -1. In the other periods the d and f subshells are involved in the transtion metals and lanthanides and actinides. As you go from group 18 to group 13 there is a steady reduction beyond that the situation is a bit more complex. Check the electron configurations of each elemnt if you need to go to this depth.

∙ 9y agoIn any given column of the Periodic Table the number of valence electrons remains the same, with the exception of the transition metals which can swap a few electrons between the valence shell and internal shells (resulting in what is referred to as multiple oxidation states).

The number of valence electrons must increase as you are also adding protons (as shown by the increasing atomic numbers).

What are positive and negative charge?
Positive charges are in protons and negative charges are in electrons. Neutron have neutral charges. In an atom the nucleus has protons and neutrons in it with a positive charge overall. Around the nucleus are electrons in orbitals, probable electron locations, they have a negative charge so the overall charge of an atom is neutral because the number of electrons and the number of protons are equal which is also the atomic number. To find the number of neutrons in an atom subtract the atomic number from the atomic mass. These values can be found on the periodic table of elements.
How many valence electrons does a chlorine ion have?
Chlorine is number 17 in the periodic table, so using the electron shell arrangement,2:8:7:It has 7 electrons in its valance shell so its charge becomes Cl7+ when these 7 electrons are 'donated' (= lost to, as reductant) to oxygen (only in oxyacid or salt perchlorate).Other valence values are +5, +3 and +1 in oxyacids: chlorate, chlorite and hypochlorite, respectively.
What information does the periodic table provide?
The basic periodic table shows an element's symbol, an atomic number, and they are arranged by it's group which is vertical column, and it's period which is horizontal row. The expanded table gives more information about each element, such as atomic mass, electronegativity and other values. It also tells you the atomic number, how many electrons, and neutrons are there in the symbol. The element. towards the left on the table are metals. The elements towards the right on the table are non-metals. The number of each element has on the periodic table is the number of protons that the element contains. It has the number of outer energy levels.A periodic table can tell you: How many protons, neutrons, and electrons are in a single atom of the element. If it is a metal, metalloid, or a non-metal. How many electrons are in the valence shell. And which family the element belongs to.All of the elements that have been discovered by man. They are listed in order of increasing atomic number, in rows (periods) and columns (groups) that show related characteristics.The periodic table shows the element's symbol and its atomic number, with period and group headings at the side and top, and often colors to designate related groups and subgroups.It tells what an element is classified as and it tells the atomic mass of each elementElement's name, atomic symbol, atomic number & mass, number of neutrons, protons, and electrons, its group, if its a metal nonmetal or metalloid, and number of valence electrons.First of all you can read the atomic number, which is the value of the number of protons in the nucleus and this is equal to the number of electrons of the atomic element.symbol and name of the elementatomic number (hence number of protons / electrons)mass number (hence number of neutrons)electronic configurationwhether the element is solid, liquid or gasWhether the element is metal, metalloid or non-metalSome versions of periodic tables will even list electronegativities or atomic size.The periodic table tells us the Chemical Symbol for each element, the Atomic Weight/Mass, also the name and the charge.The position of each element also corresponds to it's electron configuration, and the relationships of the positions can also be used to understand how they chemically react to one another. Full understanding of the periodic table can be an invaluable reference tool to know what reacts with what, and what kinds of bonds they make, how they position themselves against others in a molecule, and more. Sadly, rarely are these traits of the periodic table taught.
Facts about Linus Pauling?
chemist who assigned "Pauling values" to every element in the periodic table, setting fluorine (the most electronegative) to 4.0 and basing every other elements electronegativity of of that number.
Why do nonmetals have higher ionization energies?
Non metals have high ionisation energies, since they tend to gain electrons. They have more electrons in the valence shell compared to metals, therefore more energy is required to remove them. They also have more protons, which is essentially the pulling power, therefore the electrons are closer and more energy is required to remove them.
How do you find out how many protons and electrons there are in gold?
look at the periodic table and find its atomic number that is the number of protons and electron because their values are the same

How many electrons have quantum numbers values n l m?
In theory, the number of electrons with each quantum number is not limited. However, for any given "main quantum number" (n), the number of electrons having the other quantum numbers is limited - but it depends on the value of "n". For more information, the Wikipedia article on "quantum number" seems to give a good overview.
determine the subatomic particle ( electron, protons, neutron)?
For Example:- Calculate the number of protons, electrons, neutrons in Bromine with atomic number 35 and mass number 80. Hint: In order to answer this question you must recall the periodic properties and mole concept chapter in which you have done conversions regarding the number of moles, number of atoms, number of electrons, protons, and neutrons in a sample of given atomic number and mass number. Firstly, find the number of protons and the same number of electrons will be there and the sum of protons and neutrons form the mass number and you will get your answers. Complete step by step answer: Step 1: In this step we will find the number of protons of the given sample: Number of protons of a sample = Atomic Number of the element = 35 Step 2: In this step we will find the number of electrons of the given sample: Number of electrons of a sample = Number of protons = 35 Step 3: In this step we will find the number of neutrons of the given sample: Number of neutrons of a sample = (Mass number - Atomic Number) of the element Number of neutrons of a sample = 80 – 35 = 45 So, here we got our required values. The values are: No. of proton p = 35 No. of neutron n = 45 No. of electron e = 35 Note:The number of protons in the nucleus of the atom is equal to the atomic number (Z).The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).

How many electrons the third energy level can hold and explain why this is the case?
For each level (main quantum number) number "n", there are 2 times n squared electrons. The reasons are related to the Pauli Exclusion Principle, meaning that no two electrons can have the same values for all four quantum numbers.
The possible values of an electron spin quantum number are?
Just two, +1/2, -1/2. These correspond to electrons of opposite spin.
