RUDIKE [14]3 years ago

Answer:

High melting points and boiling points

Aqueous solutions are good conductors of electricity

Explanation:

The oppositely-charged ions have strong attractions for each other, so it takes much energy to separate them.

When the ions are the molten state or in aqueous solution, they are free to move towards the oppositely-charged electrodes. The movement of charge constitutes an electric current.

Describe the structure of the beryllium atom. In your answer make reference to the number of sub-atomic particles and where they

dusya [7]

Answer:

The nucleus consists of 4 protons (red) and 5 neutrons (orange). Four electrons (white) occupy available electron shells (rings). The stability of an element's outer (valence) electrons determines its chemical and physical properties. Subatomic particles are particles that are smaller than the atom. Protons, neutrons, and electrons are the three main subatomic particles found in an atom. Protons have a positive (+) charge. An easy way to remember this is to remember that both proton and positive start with the letter "P."

hope this helped:)

How do alpha particles compare to gamma rays?

Fofino [41]

Answer:

Unlike alpha and beta particles, which have both energy and mass, gamma rays are pure energy. Gamma rays are similar to visible light, but have much higher energy. Gamma rays are often emitted along with alpha or beta particles during radioactive decay.

What is the oxidation state of the underlined atom in the reaction:

kvasek [131]

Answer:

Explanation:

Let's consider the following balanced equation.

Mn(NO₃)₂ + 2 HCl --> MnCl₂ + 2 HNO₃

We can determine the oxidation number of N in (NO₃)₂²⁻ taking into account that the sum of the oxidation numbers of the elements present in a chemical species is equal to this overall charge. For this compound we know:

The oxidation number of O is -2.
The overall charge is 2-.
We have 2 atoms of N and 2× 3 = 6 atoms of O.

2 N + 6 O = 2-

2 N + 6 (-2) = 2-

2 N = +10

N = +5
