Answer:
ions
Explanation:
Individual atoms of the same element but having slightly different number of protons and electrons are called ions.
Ion is a charged particle.
- An atom is made up of three fundamental subatomic particles.
- Protons are the positively charged particles
- Electrons are the negatively charged particles
- Neutrons do not carry any charges.
When the number of protons > electrons the body is positively charged.
When the number of electrons > protons the body is negatively charged.
Charged particles are called ions.
Answer:
0.84kg of gatorade powder
Explanation:
From the question given, we were told that 0.6kg of gatorade powder required 5 gallons of water.
To obtain the mass of gatorade needed for 7 gallons of water, we simply do the following:
0.6kg of gatorade powder required 5 gallons of water.
Therefore, xkg of gatorade powder will require 7 gallons of water i.e
xkg of gatorade powder = (0.6 x 7)/5
xkg of gatorade powder = 0.84kg
Therefore, 0.84kg of gatorade powder will be required.
A molecular formula tells us the atoms involved in bond, what kind of atoms are involved and the ordinality of the atoms. This tells the number of atoms found in the molecule. This can be used to derive the stoichiometric ratios of different atoms. The answer to this problem is a. True.
Answer:
Explanation:
1 . periodicity
repeating nature of atomic structure
Periodicity is the repeating nature or trend of an atom on the periodic table. Periodicity can be inform of ionization energy, atomic radius, nuclear charge etc.
2 . shell
location of an electron
Electrons are located in shells. It is where electrons are found in an atom and the probability of finding electrons there are high
3 . non-metals
high ionization energies
Non-metals have high ionization energies which is the energy required to remove a loosely bonded electron in an atom. Metals have low ionization energies.
4 . noble gases
least reactive family
Noble gases are called inert gases. They have complete electronic configuration and this makes them unreactive.
5 . neutral
charge on a neutron
Neutrons have no charge on them. They are subatomic particles found in the nucleus alongside the protons
6 . repel
like charges
Like charges repel one another
7 . attract
unlike charges
Unlike charges attracts. Positve attracts negative charges.
Answer:
B. An equation that shows only those particles involved in the reaction, and that is balanced for both mass and charge
Explanation:
A net ionic equation is a chemical equation that will only show the elements, compounds, and ions that are directly involved in the chemical reaction. It comes from the balanced molecular equation and should be balanced by both mass and charge.
