Atoms that have become negatively charged by gaining extra electrons are called

Chemistry
1 answer:
VLD [36.1K]3 years ago
4 0

Answer:

CATION

Explanation:

If an atom has an equal number of protons and electrons, its net charge is 0. If it gains an extra electron, it becomes negatively charged and is known as an anion. If it loses an electron, it becomes positively charged and is known as a cation.

Ain___accepts electrons and becomes___
Serga [27]

<u>Answer:</u>

<em>An atom accepts electrons and becomes an anion.</em>

<em></em>

<u>Explanation:</u>

Atomic number = number of electrons = number of protons.

Atomic number of sodium is 11

So the atom contains 11 protons and 11 electrons

To find the number of neutrons we make use of the formula  

Mass number - atomic number = number of neutrons

From the periodic table, we know mass number of sodium is 23

So number of neutron = 23 - 11 = 12.

When a sodium atom loses an electron it will have 11 positive protons and 10 negative electrons. Since 1 positive charge is more, Na becomes Na^+.

Positively charged ion is called as cation

Chlorine's atomic number is 17 so it has 17 protons and 17 electrons.

When it gains an electrons, it will have 17 positive protons and 18 negative electrons. Since 1 negative charge is more, Cl becomes Cl^-.

Negatively charged ion is called as anion.

The sum of the protons and neutrons in an atom equals the?
Shalnov [3]

Answer:

mass number

Explanation:

The sum of the protons and neutrons in an atom equals the mass number of such an atom.

  • Mass number is the mass of an atom.
  • The mass of an atom is concentrated in the nucleus
  • The particles in the nucleus are the protons and neutrons.

So;

Mass number = number of protons + number of neutrons.

Enter your answer in the provided box. On a certain winter day in Utah, the average atmospheric pressure is 718 torr. What is th
AnnZ [28]

Answer:

The correct answer is 0.047 mol/L

Explanation:

The atmospheric air is a mixture of gases. We can assume an ideal behavior of the gas and use the ideal gas equation:

PV= nRT

where P is the pressure, V is the volume, n is the number of moles, R is a constant (0.082 L.atm/K.mol) and T is the temperature in K.

We have to first convert the pressure from Torr to atm:

760 Torr= 1 atm

⇒ 718 Torr x 1 atm/760 Torr = 0.945 atm

Then, we convert the temperature from ºC to K:

0ºC = 273 K

⇒ -29ºC+273= 244 K

Finally, we introduce the data in the equation and calculate de densitiy, which is the moles per liters of gas (n/V):

PV = nRT

n/V= P/RT

n/V = (0.945 atm)/(0.082 L.atm/K.mol x 244 K) = 0.047 mol/L

Is it possible to produce a blood type AB from blood type A and B
Masja [62]

Answer:

Yes, it is possible to produce a blood type AB from blood type A and B.

Explanation:

If we were to do a hybrid cross and the mother's blood type was A, then her genotypes would be AA and AO. Additionally, if the father had type B blood, his genotypes would be BB and BO. From this, we can tell that the child's genotypes would have to be A, AB, B, O. Since AB is one of the choices, yes, it is possible to produce a blood type AB from blood type A and B.

The only times where you won't be able to produce a child with type AB is if both of the parents have type B blood and type O blood. Or if one parent has type B blood and the another has type O blood. Or if one parent has type AB and the other one has O blood. Or if both parents have type A blood.
