The general form of a compound can be written in the form
of:
[X(a) Y(b)] ^ c
Where a and b are subscripts, and c is the superscript of
the whole formula.
The relationship that we can derived here between the
constants is:
(valence of X) * a + (valence of Y) * b = c
Since the formula obviously has no superscript, therefore
c = 0. We also know in chemistry class that the valence of Cl is -1, therefore:
valence of X * 1 + (-1) * 3 = 0
valence of X - 3 = 0
<span>valence of X = 3</span>
Answer:
Elements with low ionization energies.
Explanation:
The ionization energy of an atom reffers to the amount of energy that is required to remove an electron from the gaseous form of that atom or ion.
The greater the ionization energy, the more difficult it is to remove an electron. The ionization energybis one of the indicator that shows the reactivity of an element. Elements with a low ionization energy such as metals are usually reffered to as a reducing agents and form cations, this give metals the tendency to
give away their valence electrons when bonding, whereas non-metals tend to take electrons.
Metallic elements have different properties such as shiny, heat and electricity conductivity . They are malleable and ductile Some metals, such as sodium, are soft and can be cut with a knife. while some are very hard such as iron.
Answer:
FBr is a chemical formula representing "flourine monobromide."
Explanation:
Of course, FBR could represent a number of things, from the Federal Board of Revenue to a fluidized bed reactor. I gave the answer I did because you listed this question as Chemisty.
Answer:
Both have the same amount of particles.
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02×10²³ particles.
This implies that 1 mole of Hydrogen contains 6.02×10²³ particles. Also, 1 mole of oxygen contains 6.02×10²³ particles.
Thus, 1 mole of Hydrogen and 1 mole of oxygen contains the same number of particles.
