Answer:
The answer is: the number of unpaired valence electrons
Explanation:
The valence electrons are the number of electrons present in outer shell of an atom that participate in chemical bond formation, if the outer shell is not completely filled.
Covalent bond formation occurs when two atoms contribute one valence electron each to form a bond. Thus the number of covalent bonds that an element can form, can be determined by the number of unpaired valence electrons.
Therefore, the nature and the number of bonds formed by the element and the chemical properties of the element can be determined by the number of valence electrons present in the outer shell of the element.
Hi there ,
Electron represents atomic number.
Protron and Neutron determine the weight.
Hope it helps.
Answer:
Recall that, at the boiling point, we observe that both liquid and gas are at equilibrium with one another. This is true at every combination of applied pressure and boiling point temperature. ... The applied pressure will be greater than the vapor pressure, and all of the gas will condense into the liquid
Answer:
a)22.2°C after adding magnesium
b)17.3°C before adding magnesium
c) 4.9 is change
Answer:
19.99
Explanation:
The steps are what I did, so no need to do it the exact same!
1. Add 4.50 and 3.4
4.50 + 3.4 = 7.9
2. Add 7.9 and 12.09
7.9 + 12.09 = 19.99
Hope this helps!
