What element has 80 protons, 81 neutrons, 79 electrons?

Answers

Answer:

The element will be [tex]^{161}_{80}X[/tex]

Explanation:

Given that,

Number of proton = 80

Number of neutron = 81

Number of electron = 79

We know that,

The atomic number is equal to the number of proton.

So, the atomic number is 80.

According to atomic number,

The element will be mercury.

We need to calculate the atomic mass

Using formula of atomic mass

[tex]atomic\ mass=atomic\ number+number\ of\ neutron[/tex]

Put the value into the formula

[tex]atomic\ mass=80+81[/tex]

[tex]atomic\ mass=161[/tex]

We need to find the element

Using atomic mass and atomic number

[tex]atomic\ mass\ number A=161[/tex]

[tex]atomic\ number Z=80[/tex]

So, the element will be

[tex]^{A}_{Z}X[/tex]

Put the value of A and Z

Hence, The element will be [tex]^{161}_{80}X[/tex]

d) earth has gravity

Answers

The correct answer would be we have no other frame of reference besides the sky. We could actually tell we are moving because of the shifting of stars in the sky over time. But really, “A” would be your answer. We have the same momentum of the earth. It’s like being on a train at a constant speed. The only way you know you’re moving is if you look out the window or the speed changes causing you to be pushed around. Same thing with earth, our only reference is the sky

Answer:

The Nitric Acid Test

Explanation:

The Nitric Acid Test is used to check if silver is pure or plated. To do so, file a small part of the item in a discreet area where it cannot be seen. Apply a few drops of nitric acid.
