35 Which element reacts with oxygen to form ionic bonds?(1) calcium (3) chlorine

Chemistry

QveST [7]2 years ago

Covalent bonds exist between two nonmetal elements while ionic bonds exist between a metal and a nonmetal element. In this case, oxygen is a nonmetal and in order to create an ionic bond, the other substance should be a metal. The answer therefore to this problem is calcium.

\boxed{\left( 1 \right){\text{ calcium}}} reacts with oxygen to form ionic bonds.

Further Explanation:

Covalent bonds are the types of bonds that involve the sharing of electrons between the bonded atoms. This bond is usually formed between two or more non-metals.

Ionic bonds are the chemical bonds that involve the transference of electrons from one atom to another. These bonds are generally formed between metals and non-metals. In these types of bonds, ions are formed by the atoms. Cations are formed by the loss of electrons and anions result from the gain of electrons.

Oxygen is a non-metal. In order to form an ionic bond with oxygen, the other element has to be a metal.

Hydrogen, chlorine, and nitrogen are non-metals so these can form covalent bonds with oxygen. But calcium is a metal and it forms ionic bonds with oxygen. Calcium loses two electrons to form {\text{C}}{{\text{a}}^{2 + }} and these electrons are gained by oxygen, resulting in the formation of {{\text{O}}^{2 - }}. The attraction between {\text{C}}{{\text{a}}^{2 + }} and {{\text{O}}^{2 - }} is an ionic bond and the resulting compound is CaO (For structure, refer to the attached image).

Can someone help me with number 1 and 2 plz!
GalinKa [24]

Answer:

1) 0 N

2) 8 N

Explanation:

The net force is the sum of all of the forces acting on the object.

For question 1, we can see that there is a force of 5 N acting to the right and 5 N acting to the left.  If we define the right to be positive and the left to be negative, then the net force equals:

Fnet = 5N - 5N = 0 N

Therefore, the net force in question 1 is 0 N.

For question 2, the process is very similar.  We want to find the sum of the forces acting on the object.  In this case, there are forces of 3 N and 5 N acting to the right.

Fnet = 3 N + 5 N = 8 N

Therefore, the net force in question 2 is 8 N.

Hope this helps!

If a neutral atom has 24 electrons and 26 neutrons how many protons does it have?​
Salsk061 [2.6K]

Answer:

24

Explanation:

The number of protons in the atom of the neutral element will also be 24.

Protons are the positively charged particles in an atom.

Electrons are the negatively charged particles

Neutrons do not carry any charges at all

Now, in a neutral atom, the charge is balanced and the number of protons and electrons are the same in the atom.

So, since we have been given that the atom has 24 electrons, the number of protons will be 24.

Which of the following symbols represents a chlorine ion with a stable arrangement of eight valence electrons?
frozen [14]

A stable arrangement of eight valence electrons : ³⁵Cl⁻¹

<h3>Further explanation</h3>

Chlorine is a halogen gas, located in group 17, p block

Chlorine has an atomic number of 17 and an atomic mass of 35

Electron configuration: [Ne] 3s²3p⁵

If we look at the electron configuration, then Cl will bind 1 more electron so that the configuration is stable like Argon (atomic number 18)

So by binding this one electron, chlorine forms negative ions (anions)

³⁵Cl⁻¹

B. Cl⁻² binds 2 electrons, exceeding the octet rule

C. Cl⁺¹, releases 1 electron, remains unstable

D. Cl, the neutral form of Cl, is still unstable with a 7-electron valence configuration

what is the half life isotope if after 21 days you have 31.25 g remaining from a 250.0 g starting sample size?
alexgriva [62]

250 --> 125 --> 62.5 --> 31.25


each arrow equals one half life, so 3 half lives


14 days/ 3 half lives =


4.67 days = half life
