Answer:

± 1 or ± 2

Explanation:

Electrovalent bonds are chemical bonds that are established on the premise of transferring electrons between two atoms.

In this bond type, a higly electronegative atom, typically a non-metal receives electrons from an atom with lesser electronegativity, a metal.

To know the number of electrons involved in forming electrovalent bonds, we typically look at the groups of atoms that combines to form the bond.

Metals are found in group I and II on the periodic table. Metals are electropositive and are good electron donors. These metals have 1 and 2 electrons in their valence shell respectively. In like manners, the more electronegative atoms are found in group VI and VII. The elements in these groups are non-metals with high electronegativity and requires just 1 and 2 electrons to complete their octet.

zhenek [66]

Answer:

Nitrogen

It has the least number of protons in the group hence making it smaller

Explanation:

According to periodic table, electronegativity increases across the period and decreases down the group.

Electronegativity is the tendency of an element to accept electrons towards itself.

In this group of elements, nitrogen has the highest electronegativity because it has the least number of protons in the group. Increase in the number of protons decreases an elements electro negative value.

The least electronegative element in that group is Antimony (Sb).

Electronegativity increases across the period and decreases down the group while electropositivity decreases across the period and increases down the group.

1. In order to make 1 salad it requires 1 head of lettuce, two tomatoes and three carrots. What would be the coefficients for th
pogonyaev

Answer:

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots

Coefficients: 3, 6, 9

Explanation:

1 salad = 1 lettuce + 2 tomatoes + 3 three carrots

<em>Multiply all the coefficients of 1 salad by 3:</em>

3(1 salad) = 3(1 lettuce + 2 tomatoes + 3 three carrots)

<em>Expand the equation:</em>

3 salad = 3 lettuce + 6 tomatoes + 9 three carrots

The nuclear mass of 56fe is 55.9207 amu. calculate the binding energy per nucleon for 56fe.
Aneli [31]

Fe (iron) has 26 protons,30 neutrons and 26 electrons. In order to calculate the binding energy, first you need to find the total mass of all particles in the nucleus:

<span>
<span>26 x mass of proton + 30 x mass of neutron ( all in a.m.u.) = say "m" </span></span>

<span>
Mass defect is m- 55.9207 amu, then convert it into grams and put in equation E = mc2 to get binding energy of Fe.</span>

<span> Divide it by number of nucleons to get binding energy per nucleon</span>.
