# How many fluorine atoms bond with calcium to form calcium fluoride?

2 fluorine atoms

Explanation;
• Calcium, a Group 2 metal, commonly forms a calcium ion (Ca2+). On the other hand, fluorine, a Group 7 non-metal, commonly forms a fluoride ion (F-). The necessity of electrical neutrality ensures that 2  Fluoride ions (F-) binds to one Ca2+
• The charge on calcium is 2+ and the charge on fluoride ions is 1-. It therefore requires 2 fluoride ions to make the compound electrically neutral.
Answer: 2 charge on calcium is 2+ and the charge on fluorideions is 1-. It therefore requires 2 fluoride ions to make the compound ..

If you are in a relationship with someone how do you show them you care instead of being mean to them?

If you really like/love her/him don't just say it put it in action. and lastly tell them and show them how much you care.

Gravity on Earth is 9.8 m/s2, and gravity on the Moon is 1.6 m/s2. So, if the mass of an object on Earth is 40 kilograms, its mass on the Moon is ????? kilograms and its weight on the Moon is ???? newtons.

The mass of an object on Earth is the same as its mass on the Moon. The weight is different.
Weight = m * g
Weight ( Moon ) = 40 kg * 1.6 m/s² = 64 N
If the mass of an object on Earth is 40 kg, its mass on the Moon is 40 kg and its weight on the Moon is 64 N.

the weight of the object on the moon is 64 N and the mass on the moon is 40 kg
