Answer:

Barium and sulpher are the elements that forms barium sulphide .

And its molecular fomula is BaS.

Explanation:

There are two types of chemical compound one is covalent compound and other is ionic compound, covalent compound formed by sharing of electron and ionic compound formed by complete transfer of electron. Therefore, in barium sulfide, barium and sulfur elements are present.

What is chemical Compound?

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

An ionic compound is a metal and nonmetal combined compound.  Ionic compound are very hard. They have high melting and boiling point because of strong ion bond.  In barium sulfide, barium and sulfur elements are present. The molecular formula of the compound is BaS.

Therefore, in barium sulfide, barium and sulfur elements are present.

If atomic size is the distance from the nucleus to the valence electrons, does the size of the atom get bigger or smaller as you go from period 1 to 3? Explain?

Answers

Smaller the atomic size get smaller as it goes across a period. This is because periods all have the same amount of valence electron shell numbers (like period 2 has 2 valance shells around the atom) but at the same exact time, the number of protons increase going down the period. This means there’s more/a stronger pull from the protons to the outer balance electrons making the valance electron layers pull inward more, but on the next layer of new balance electron shell is formed so the distance between the outer most balanced electron in the protons is wider than the previous level, but like before the gap decreases as a you go down the period.

In such a way, since there is 1:3/2 mole ratio between methanol and oxygen, we can compute the moles of oxygen that are needed to burn 2.56 moles of methanol as shown below:

b. an atomic number 13

c. 26 electrons

d. 26 protons

I believe b. an atomic number 13. is the answer.

Answers

B is correct please thank me by pressing heart

The atomic weight of Aluminum (AL) is 26.98. It has 14 neutrons. Aluminum has  an atomic number 13. Therefore, option B is correct.

What is atomic number?

The atomic number of an element represents the number of protons in the nucleus of its atoms. Since the atomic number of an element is unique and determines its position in the periodic table, aluminum has an atomic number of 13.

The number of electrons in a neutral atom is equal to the number of protons, which in this case is 13. Therefore, aluminum has 13 electrons.

The atomic weight of aluminum (Al) is 26.98, which represents the weighted average mass of all the naturally occurring isotopes of aluminum, taking into account their relative abundances. The number of neutrons in an atom of aluminum is given as 14.

Thus, the correct option is B.
