How do you find how many electrons are in a atom?

Chemistry
1 answer:
seropon [69]3 years ago
4 0

Answer:

To determine how many total electrons there are, add the amount of charge to the atomic number. In this case, there are fewer protons than electrons. For example, N 3- has a -3 charge which means it has 3 more electrons than a neutral nitrogen atom. Nitrogen’s atomic number is 7, therefore this ion has 10 electrons.

Answer:

Cross-pollination

Explanation:

This technique is used to create new varieties, usually with stronger characteristics than the two original varieties. When the pollen of <u>one variety</u> is placed to a <u>different plant's stigma</u>, the resulting seeds create a new variety. This cross-pollination is used in plants of the same species.

A metal is found that has a mass of 27g and will displace 6mL of water. Calculate its density and identify the metal.
melisa1 [442]

The density of metal = 4.5 g/ml, and the metal = Titanium

<h3>Further explanation  </h3>

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

Density formula:  

\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}

ρ = density  

m = mass  

v = volume  

mass of metal=27 g

volume = 6 ml

The density :

\tt \rho=\dfrac{27}{6}\\\\\rho=4.5~g/ml

The metal with a density of 4.5 g/ml is Titanium

I need help on 5,6,7. I would give you guys a thank you. This is going to be due very soon.
Ira Lisetskai [31]

Answer:

5) Plant; 6) Heat; 7) never heard of chemosynthesis, sorry :(

Explanation:

A plant is the only thing in an ecosystem that uses photosyenthesis. This includes trees, algea, and grass.

80% of energy is lost as heat used in order to keep the animal warm.

I am really sorry I couldn’t help with 7!

What action would you expect an atom of Aluminum to undergo?
KATRIN_1 [288]

Answer:

C. Lose three electrons to have a full outer shell  

Explanation:

Al is in Group 13 of the Periodic Table, so it has three valence electrons.

It must either lose three electrons or gain five to achieve a stable octet.

It is easier to lose three electrons than it is to gain five, so Al loses three electrons.

D. is wrong, for the same reason.

A. is wrong. If Al lost three electrons, it would be breaking into a stable inner shell.

C. is wrong. Al is a metal, so it will lose electrons in a reaction.
