Answer:

The correct option is Both of their ions will have a charge of +2

Explanation:

The periodic table has vertical columns called the group and horizontal rows called periods. Elements in the same group have the same number of electrons in their outermost shell - for instance elements in group 1 have just one electron in there outermost shell and elements in group 2 have two electrons in their outermost shell.

When elements (usually metals) lose/donate the electron(s) in their outermost shell, they become positively charged and when non-metals gain electron(s) that are added to their outermost shell, they become negatively charged. Elements in group 2 will lose the two electrons in their outermost shell to become positively charged having a charge of +2 to show they have lost/donated the two electrons in there outermost shell.

- You have to understand the overall concept

Elements in group 2 have 2 electrons in their outer shell and would lose 2 electrons to form 2+ions.

If you think about it, it makes sense.

An element itself has no charge as the number of protons and electrons but if it loses 2 electrons, it will have 2 more protons than electrons.

In short, your answer is 'both of their ions will have a charge of +2'

Have A Nice Day ❤

Number 39! Please explain step by step!!!
ahrayia [7]

Answer:

The answer to your question is The honda civic hybrid weights 13181.8 N or 1318.2 kg

Explanation:

Data

Weight = 2900 lb

Weight = ? N

mass = ? kg

1 kg ------- 10 N

0.22lb ---- 1N

Use proportions to solve this problem

                        0.22 lb ------------------- 1 N

                        2900 lb -----------------  x

                         x = (2900 x 1) / 0.22

                         x = 2900 / 0.22

                        x = 13181.8 N

                          1 kg ----------------------- 10 N

                           x     ----------------------- 13181.8 N

                           x = (13181.8 x 1)/10

                           x = 1318.2 kg

b) We are capable of writing with a pen due to the friction between the pen and the paper.

FRICTION DISADVANTAGES:

b) Forest fires are caused due to the friction between the trees branches

How is ti possible that, when adding protons while moving left to right across a period, the size of an atom shrinks? Why is the
Kaylis [27]

As one moves across a period, from left to right, both the number of protons and electrons of a neutral atom increase. The enhancing number of electrons and protons results in a greater attraction between the electrons and the nucleus. This uplifted attraction pulls the electrons nearer to the nucleus, therefore, reducing the size of the atom.  

On the other hand, while moving down a group, there is an increase in the number of energy levels. The enhanced number of energy levels increases the size of the atom in spite of the elevation in the number of protons. In the outermost energy levels, the protons get attracted towards the nucleus, however, the attraction is less due to an increase in the distance from the nucleus.

Calculate the molarity of hydroxide ion in an aqueous solution that has a poh of 5.00
Simora [160]

Answer:

1.00 x 10^-5 M

Explanation:

pOH=-log[OH^-]

so

[OH^-]=10^(-pOH)

=10^-5

=1.00 x 10^-5 M
