Write the chemical symbol for three different atoms or atomic cations with 22 electrons
damaskus [11]

Answer:

Explanation:

To write the chemical symbol for an atom or cation with 22 electrons, we must understand some few things about an atom.

An atom is made up of positively charged paticles called protons which are located in the nucleus. The neutrons do not have any charges and are they reside together in the nucleus with the protons.

Electrons are negatively charged particles which orbits the nucleus.

Titanium in its neutral state is the 22nd element on the periodic table and it has 22 electrons.

Vanadium is the the 23rd element on the periodic table. If it loses an electron, it becomes positively charged and it is a cation.

Chromium is the 24th element on the periodic table. A loss of two electrons makes the net electrons remaining on it 22.

The symbols are:

       ₂₂Ti

        ₂₃V¹⁺

        ₂₄Cr²⁺

As the elements in period 2 of the Periodic Table are considered in order from left to right, which property generally decreases
nadya68 [22]

Answer:

Atomic radius

Explanation:

Atomic radius

As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required.

Atomic radii trend along group:

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

A capacitor has a peak current of 310 μa when the peak voltage at 300 khz is 3.0 v .
Ket [755]
I think the question for this problem, is to find the capacitance. The working equation would be:

C = Q/V,
where
Q = It

Since f = 1/t, t = (1/300 kHz)(1 kHz/1,000 Hz) = 3.33×10⁻⁶ s
So,
Q = (310×10⁻⁶ A)(3.33×10⁻⁶ s)
Q = 1.033×10⁻⁹ C

Thus,
C = (1.033×10⁻⁹ C)/(3 V)
<em>C = 3.44×10⁻¹⁰ F</em>

Atoms of elements at the top of a group on the periodic table or smaller than the atoms of elements at the bottom of the group.
castortr0y [4]
Generally speaking the larger, more massive elements are less stable, like isotopes of elements. With this said, they are less likely to react since they will become heavy and unstable. This is why chlorine is more reactive with other elements like sodium than astatine.
