Answer:

Electronegativity increases across the period on a periodic table.

Explanation:

Electronegativity is the ability of an atom to attract electron to itself.

All elements on the periodic table combines in order to have a complete octet i.e they all want to be like the noble gases, group 0 elements.

This is what drives most atom to combine chemically. By so doing, they either lose or gain electrons.

Cl belongs to the 7th group on the periodic table. It is the second element in this halogen group. Most halogens are notable for their high electronegativity. They have 7 electrons in their outermost shell and would require just an electron to complete their octet.

This makes them highly reactive and combine readily with other elements.

The halogens have a strong attraction for valence electrons. The higher the electronegativity value, the stronger the attraction an atom has for valence electrons.

Most metals like Al and Na are electropositive and readily donates or lose electrons so as to have a complete octet.

Explanation:

The given elements Na, Al, P and Cl are all elements of period 3.

Atomic number of sodium is 11 with electronic distribution 2, 8, 1.

Atomic number of aluminium is 13 with electronic distribution 2, 8, 3.

Atomic number of phosphorous is 15 with electronic distribution 2, 8, 5.

Atomic number of chlorine is 17 with electronic distribution 2, 8, 7.

An element that has the tendency to readily attract an electron towards itself is known as an electronegative element.

So, out of the given elements chlorine is the most electronegative. Hence, an electron will be most strongly attracted to chlorine.

Can someone plz explain ionic and covalent bonding plzzzz!!!
Alexeev081 [22]

Answer:

Ionic Bonding: The formation of an Ionic bond is the result of the transfer of one or more electrons from a metal onto a non-metal.

Covalent Bonding: Bonding between non-metals consists of two electrons shared between two atoms.

[HELP PLEASE] Describe the difference between the ways valence electrons are rearranged when forming ionic bonds and covalent bo
nydimaria [60]

Answer:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

The pictures are the answers
Mice21 [21]

Answer:

C.

Explanation:

If the students want to know at what percent of CO2 in the air the plant will grow at the fastest, then the percent of CO2 should be a different value for each plant in the table.

There are 2 tables that have different values for the CO2 - the tables in answer choices C and D.

Since the students only want to know how the amount of CO2 affects the plant, every other variable should remain constant.

The only answer choice that has a changing value for the percent of CO2 and a constant value for every other variable is C.

Whats the difference between a solution and a compound? (sorry if this is funny to ask)
Kipish [7]

Answer:

A compound is just pure  that is composed of elements that are chemically bonded in definite proportions

andd solution is umm well its a homogenous so basically saying

that it all just stays the same all the way through  

Explanation:

im not sure how else to explain it haah hope this helped  :P
