Answer:

D) How many valence electrons the atom contains.

This is the only closest one

because the number of electrons in the outermost shell is the correct answer

An atoms reactivity can be determined by how many valence electrons the atom contains.

Answer: Option D

<u>Explanation: </u>

The tendency of elements to react with each other depends on their electronegativity. An element having higher electronegative value will react easily with other elements. So, an electronegative elements tends to have highest reactivity.

Some of the elements in the periodic table does not react with any other elements, they are the noble elements as their electronegativity values are zero. All are elements present in a single group exhibit common electronegative.

And, the measure of electronegativity is done by the number of electrons in the valence shell or in other terms the number of valence electrons. Thus, the valence electrons count decide the reactivity of an atom.

Answer:

neon gas

Explanation:

neon is a noble gas, meaning it has a full outer shell of elections. this means it is stable and is very unlikely to have a reaction with another substance.

Are these radiation, conduction, or convection?
irakobra [83]
Hey! 1) Convection [Warm water is less dense, so it rises.] 2) Conduction [The metal skewer is heated by the fire, and it is directly touching your hand. The metal skewer transfers heat to your hand through conduction.] 3) Conduction [The rock is directly touching you, so it transfers heat to you through conduction.] 4) Convection [Convection causes weather systems because hot air sinks and cold air sinks] 5) Convection [The hot air rises because it is less dense while the cold air sinks because it is denser.] ~Hope this helped~

2074 Set B Q.No. 1 What mass of nitrogen will be requires
timurjin [86]

140 g of nitrogen (N₂)

Explanation:

We have the following chemical equation:

N₂ + 3 H₂ -- > 2 NH₃

Now, to find the number of moles of ammonia we use the Avogadro's number:

if        1 mole of ammonia contains 6.022 × 10²³ molecules

then   X moles of ammonia contains 6.022 × 10²⁴ molecules

X = (1 × 6.022 × 10²⁴) / 6.022 × 10²³

X = 10 moles of ammonia

Taking in account the chemical reaction we devise the following reasoning:

If        1 mole of nitrogen produces 2 moles of ammonia

then  Y moles of nitrogen produces 10 moles of ammonia

Y = (1 × 10) / 2

Y = 5 moles of nitrogen

number of moles = mass / molecular weight

mass = number of moles × molecular weight

mass of nitrogen (N₂) = 5 × 28 = 140 g

How are flash drives better than hard drives
Greeley [361]
Flash drivers are more robust, if you drop it, it is still most likely to work. Hard drivers provide more storage. There’s not much difference
