3 0

Answer:

2, 8

Explanation:

Sodium Na has 11 electrons.

The electronic configuration of sodium is 2, 8, 1

Sodium loses 1 electron, the new atom has 10 electrons.

11 - 1 = 10

2, 8

Answer:

Sodium cation loses one electron, so Na+: 1s(2)2s2(2)p(6)3s(1) = Na+: 1s(2)2s(2)2p(6). P: 1s(2)2s(2)2p(6)3s(2)3p(3)

What happens to a Lithium atom for it to become an Li+1 ion?
Maru [420]

Answer:

If an atom gains or loses an electron, it bacomes an ion. An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion

Explanation:

A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion.

A fluorine atom will tend to gain, rather than lose, an electron. By gaining a negative electron, it has an overall negative charge. It has become a negative ion.

. Act 20 g Ca (M = 40g / mol) with H2SO4 diluted within 10 seconds. What will be the rate of hydrogen formation in mol / sec. pl
11111nata11111 [884]

Answer:

Rate of hydrogen formation is 0.05 mole per second

Explanation:

Firstly, we write the equation of reaction.

When alkali earth metals react with dilute mineral acid, the reaction is vigorous with the production or evolution of hydrogen gas as a result of the displacement of the hydrogen from the acid by the metal. This is one of the basic reactions of mineral acids

Ca + H2SO4 ——> CaSO4 + H2

Looking at the reaction, 1 mole of calcium gave 1 mole of the hydrogen gas

What we do now is to calculate the number of moles of calcium produced by 20g of Ca

Mathematically;

number of moles = mass/atomic mass

number of moles of calcium is thus

20/40 = 0.5 moles

Now, if 1 mole of calcium produced 1 mole of the gas

Definitely, 0.5 mole of calcium will produce 0.5 mole of the gas

So the rate of gas formation would be 0.5/10 = 0.05 mole/second
