What happens to the number of values electrons as you move from left to right in the periodic table?
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.

What is the relationship between the 3d elements on the periodic table and their electronegativity values?
The relationship between the 3D elements on the periodic table and their electronegativity values is that as you move across a period from left to right, the electronegativity values generally increase. This means that elements on the right side of the periodic table tend to attract electrons more strongly than elements on the left side. Additionally, as you move down a group, the electronegativity values generally decrease.
How do you find m sub l on the periodic table?
The M tells you which row of the periodic table you can find the element in, and the L tells you which suborbital the electron is found in. The suborbital signifies how many electrons are in the shell of the element.
What increases as you move up a column of the periodic table?
As you move up a column of the periodic table, the number of electron shells increases. This leads to a greater distance between the nucleus and the outermost electrons, resulting in larger atomic size. Additionally, the number of protons and electrons also increases, leading to a higher atomic number and different chemical properties.
The development of the periodic table created predictable trends What trend does electronegativity follow?
Electronegativity increases from left to right.
What is electropositvity?
Electropositivity is a measure of the ability of an atom to attract and hold onto electrons. Atoms with low electronegativity values are considered electropositive because they have a tendency to lose electrons and form positive ions. Electropositivity increases from left to right across a period and decreases down a group on the periodic table.
How do you find out how many protons and electrons there are in gold?
Gold has 79 protons and 79 electrons. This is because the atomic number of an element corresponds to the number of protons in its nucleus, which is the same as the number of electrons in a neutral atom.

In addition to the atomic number what other numerical values appears in the square for each element on the periodic table?
Atomic Mass
A current of 1.10 A flows in a wire. How many electrons are flowing past any point in the wire per second?
To calculate the number of electrons flowing per second, you can use the formula: Number of electrons = (Current in Amperes) * (1 Coulomb/1 Ampere) * (1 electron charge) Plugging in the values: Number of electrons = 1.1 * 6.242 * 10^18 electrons/second Number of electrons = 6.87 * 10^18 electrons/second

What are the possible values for the m1 quantum numbers for 8s electrons?
The possible values for the magnetic quantum number (m1) for 8s electrons range from -0 to 0, which means there is only one possible orientation in space. The m1 quantum number specifies the orientation of the electron's magnetic moment in an external magnetic field.
Which family of elements is the most electronegative?
Basically, the more electrons that are present in an atom, the more elctron shells it will have. Look at a periodic table and you'll see Astatine has a proton number of 85 (85 protons), as the number of electrons and protons is equal, we can therefore deduce that it has 85 electrons and is the largest halogen atom. Therefore astatine MUST have the most electron shells as it has more electrons to fill them. Basically, the more electrons that are present in an atom, the more elctron shells it will have.

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.
