Answer:
Covalent bond.
Explanation:
There are two kinds of chemical bonds: covalent bonds and ionic bonds.
- A covalent bond is formed when two atoms share a pair of electrons (two electrons for each bond.)
- Ions are formed when one atom transfers an electron to another. Ionic bonds refer to the attraction between ions of opposite electric charges.
In this example, since the atoms are sharing atoms, the chemical bond between them would be a covalent bond.
Answer:
C. 3 Li
Explanation:
Nitrogen has 7 electrons, which you can find on a periodic table. Let's figure out what its valence is, or how many electrons are in its outer shell!
We know that the first shell is filled with 2 electrons. Then the next shell is filled when it has 8 electrons, but we've only got 7 - 2 = 5 electrons left.
So nitrogen N has 5 valence electrons. That means it wants to bind with something that can offer it <u>3 electrons to share.</u>
A. 2 Ca atoms have 2 * 2 = 4 valence electrons.
B. 1 H atom has 1 valence electron.
C. 3 Li atoms have 3 valence electrons. <em>This could be our winner! Check D anyways.</em>
D. 2 C atoms have 4 * 2 = 8 valence electrons.
So the only one that works is C. 3 Li atoms.
Yes i have done that before on paper but yes its right
<span>There's a trend in electronegativity. The bottom left of periodic table is the lowest (0.7) and the upper right is the highest (4.0). The most polar is the greatest difference in electronegavity.
hbr- 1~ , hi- 0.5~ ,hcl - 1.3~ , hf-1.8 so,hf is the answer</span>
